Chapter 769 Super Casting Parts
"Old Zhou, you are in control. You are much better than me in life and work, and you are meticulous enough! I am only suitable for technology. Let's discuss the general direction. If a state-owned enterprise like Sihuan wants to acquire it, there will definitely be big waves! The development zone's
I heard that the old hydraulic parts factory has put up the land in the city for 320 million. Once the land is sold, I guess the old hydraulic parts factory will be completely shut down!"
"There is still a difference between the Fourth Ring Road and the old hydraulic parts factory. The place is rather embarrassing. The housing prices in Datun, Changchun have always been so low. National policies control it very well. The site cannot be sold or cannot be sold at all! The personnel cannot be removed and the treatment is
If you can't lower it, there are a group of bosses who are covered by the Fourth Ring Pension Insurance behind you... Liu Qing, you have to do a comprehensive investigation this time, and cooperate with Mr. Zhou to do it! If you can't do it, ask your subordinates to do it.
We must take this matter seriously!”
Ji Dongqing tried his best to calm Zhou Yunbang's emotions when he spoke, knowing in his heart that he had made another habitual mistake of technicians this time, and now he was making up for it.
Zhou Yunbang nodded frequently, and this tea party was basically considered a success. All the difficulties or depressions that everyone encountered at work this year were discussed.
Normally, Ji Dongqing is often on the line with people in China when he is abroad, but now he is checking for deficiencies.
As for the year-end bonus here, Ji Dongqing read all the documents submitted by Liu Qing and signed directly.
Zhou Yunbang and others simply checked the year-end bonuses and dividends, and then asked Xu Lijun to start making arrangements. Ji Dongqing drove straight to the foundry at the next stop.
Compared with the last time Ji Dongqing left, the size of the factory has increased by one more building this time.
The streets are no longer deserted, and from time to time you can see pedestrians coming and going, most of them workers in the foundry.
The factories that are relatively close to the foundry are now starting to be populated. What makes Ji Dongqing most concerned is that one factory is now equipped with a gantry crane.
The situation in his own factory was no less generous. When Ji Dongqing entered the workshop, Su Yue was instructing the workers to take out the ladles from the furnace.
"master!"
"Okay, what product is this?"
Watching the huge steel ladle moving slowly, Ji Dongqing also put on heat-insulating clothing with the help of his apprentice.
"Weichai's marine engine, that one over there is an order given to us by the maintenance factory of the big ship, and it is also the engine casing. This engine casing is twelve tons!"
"Fuck!"
Ji Dongqing calculated on his fingers that if the weight of the engine was multiplied by a factor, the molten steel in this ladle would weigh at least fourteen tons.
On top of the huge mold, the overhead crane was hoisting boxes of sand. Several young apprentices wearing masks began to fill them carefully. Su Yue waved her hand, and the basket came down. Su Yue and Ji Dongqing got on the truck at the same time.
"Smash it firmly and make sure there are no leaks!"
"Okay, Director Su!"
Several operators were quite old, and they were exhausted and sweating all over. The cast iron mold was filled with quartz sand, and wooden sticks were inserted in the middle of the molding sand. After being pulled out, this became a standard flow path.
This kind of heavy casting can only be successful once and cannot be processed twice. The cost of one casting is a Corolla.
"Didi!"
"Walk!"
Several sets of molds were being operated at the same time. Whistling began on the other side, Su Yue waved her hand, and Ji Dongqing's and Su Yue's overhead cranes continued to move quickly towards the other set of molds.
"Director Su, it's time to pour!"
"Attention all departments, is there any problem with ladle lifting?"
"no problem!"
"The cable is fine!"
"The crane is normal!"
"The temperature measurement is normal, 1430 degrees Celsius!"
"Remove the steel slag!"
"There is no abnormality in the flow channel at the mold mouth and it can be poured!"
"Clearing complete!"
"Start driving!"
With feedback from various departments on the intercom, Su Yue gave the order to start pouring.
The ladle containing fourteen tons of molten steel began to approach slowly. The remote control in the hands of the ground operator slowly moved, and the ladle began to slow down.
"Check the gate again!"
"The house is normal and can be poured!"
"Positive!"
"tilt!"
"Wow..."
The whitish molten steel was slowly poured into the mold along the flow channel, and suddenly smoke began to appear around the mold. Su Yue and Ji Dongqing stared at any changes on the mold.
Molten steel kept pouring around the mold, but the staff was not afraid at all until the entire ladle was poured clean.
"Return the car..."
After the pouring was completed, Su Yue ordered everyone to leave, and a cordon was put up around the mold. It would take three days for the casting to be released.
"Is it possible to take out the mold at station three, Director Su?"
"Okay, let's drive!"
Sitting on the crane, Ji Dongqing and Su Yue went directly to the other side. The huge mold was slowly being pulled up. Quartz sand continued to flow out of the mold, and the outline of the large engine slowly appeared.
"Good guy, no wonder people say that Weichai has caught up with other companies. Just one engine can make some companies half a quarter of profits!"
Ji Dongqing and Su Yue got out of the car. Su Yue handed over masks. Several welders turned on the acetylene, and several other workers took electric picks and aimed at the quartz sand above them and began to exert force. Suddenly, smoke and dust billowed.
"Ta-ta-ta-ta!"
"puff……"
With all the runners exposed, the welder waved his hands and stepped back. The welder began to cut the runners. Every time one was cut, the crane flipped the casting in one direction until the workers had cut all the gate runners cleanly.
"Get on the vibrating table!"
"The vibration table is ready and you can enter!"
Two huge cranes came slowly, and the two cranes steadily pulled up the castings and slowly sent them to the vibration table.
As the crane exits, the plastic curtain of the vibrating table is lowered, and the worker starts the vibrating platform.
"Buzz!"
"Crash..."
With the activation of the vibrating platform, the quartz sand continues to fall off, and the conveyor belt under the grid plate slowly moves forward, transferring all the vibrated sand to the molding sand recovery station.
"Master, this vibration table is made by our equipment. After the casting is finished vibrating, it will go to the shot blasting workshop for further cleaning and stress removal, and then it will enter UT flaw detection. The processing plant next door to Weichai will come one day later.
As long as there are no defective castings, our work will be completed! If nothing else happens, there will be no problems with our workpieces!”
Su Yue took Ji Dongqing along the newly completed major work stations, and introduced each work station in detail. Ji Dongqing was very pleased.
Especially for UT flaw detection, there are several parts waiting on the list at the door.
"There are not many manufacturers in Dalian that can perform UT flaw testing. In the past year, we have cooperated more and more with shipyards and Dazhong. Many of their parts are sent to us for flaw testing. In addition, we have
Isn’t our laboratory connected to the Polytechnic University? The surrounding large companies trust us very much..."
