1.2×500×2000mm深拉用黄铜板的生产工艺规程设计+CAD图纸(2)
The main production process H65 brass plate: the ingredients - melting - Component Analysis - Holding Furnace - semi-continuous casting - cut the head and tail --- two rolls of hot-rolled - cut the head and tail - Milling (double-sided milling ) - four rolls roughing - intermediate annealing (bell-type annealing furnace) - finishing - finished annealing (air cushion continuous heat treatment furnace) - cleaning - straightening - cut (vertical, horizontal shear) - finished inspection - packaging and storage.
The number of the manufacturing process to the extent of the intermediate annealing process to determine the hardening rolling, the design maximum allowable H65 brass total processing rate of 70%, and according to the design data, the design of the total working ratio of brass was 90.4%, which must be determined in order to continue rolling intermediate annealing. Calculating the number of intermediate annealing is the most important considerations as to reduce energy consumption and the rolling reduction rate to the maximum allowable working full use of the plastic deformation of the rolling member, to avoid waste of energy. When the entire annealing is complete, final cut straightening, product quality testing, confirmed that products meet the delivery requirements can be packaged in storage, waiting for delivery. Product technical requirements can be summarized as follows: the precise size good shape, high surface smooth performance to meet the technical requirements for the design of the basic premise.
This design mainly on the production of technical requirements and key H65 brass plate production process (melting, casting, milling surface, rolling and annealing) process characteristics. Chinalco Shanghai Copper Co., Ltd. in accordance with existing production processes and products, carried out on the production process of the development of smelting and rolling system preparation, roller-type system to develop, the ability to check the motor, roll strength checking, use in the design process computer software Visual Basic programming language preparation program to calculate the rolling force and rolling torque of conduct, the use of computer software Auto CAD, drawing diagrams on the roll. To design a realistic production standards and product applications.
