The first automobile factory construction and its casting technology level. The first automobile factory started construction in 1953, and the first furnace hot metal was cast on March 26, 1956, declaring that China’s first large-scale production workshop for automobile castings was completed and put into production, setting a good example for the comprehensive development of China’s automobile industry’s casting production. . The foundry's material preparation, sand processing, molding and core formation, metal melting and casting, sand casting, cooling and cleaning of the castings are all through the mold conveyor, suspension chain, scale conveyor, and belt conveyor. And bucket elevators and other transportation equipment are combined into a whole. The balance wheel sand mixer, crawler type semi-automatic shot blasting drum, continuous hanging chain shot blasting chamber, cupola furnace and electric furnace double smelting, lift type electric annealing furnace and other process equipment all have the overseas 40s and 50s. Early technology level. A large number of mechanized transport equipment will connect all processes into a complete production line. At the time, the model was a pneumatically-actuated or shock-pressure molding machine that was commonly used in the world, and six mechanized modeling flow production lines were formed by continuous or intermittent trolley-type casting conveyors. They were used for the molding of grey cast iron parts and malleable cast iron parts, respectively. The sand is sent by the belt conveyor from the sand processing department and stored in the sand bucket above the molding machine. The core of the production line is manually lowered. For the complex core groups used in the cylinder block and cylinder head, etc., they are pre-assembled, and then the cores are removed by air lifting jigs and manually boxed. The core is made of oil sand, pulp sand, and fat sand core. The core sand is made by the 辗 wheel type sand mixer; the small oil sand core is made by hand, and the large sand core is produced by the core making machine; the sand core is dried by the chain plate vertical continuous gas drying furnace. Spirals are mainly used for stirring, mixing and other functions in pipeline transportation. The spiral surface of the screw conveyor has a solid spiral surface. , belt spiral surface and blade spiral surface transparent form.

The cold rolling mill is an advanced equipment that continuously rolls blades from strip steel. By adjusting the position (roll offset, feed height, roll pressure, guide wheel, etc.), it can roll out blades of various specifications required.
Advantages of cold rolling layout:
It has the advantages of high production efficiency, saving raw materials, good blade quality, high hole diameter, and good wear resistance.
The structures that affect the rolling shape include the material and thickness of the strip, the offset of the roll, the feeding height, the rolling force of the roll, the different specifications of the guide wheels and blades, and the increase in the temperature of the roll during the rolling process. After years of construction, the contract developed this continuous cold-rolled propeller, which has the advantages of smooth surface, high hardness, wear resistance, one-time forming, and continuous no welds.
