stainless steel coils in series

stainless steel coils into austenitic, ferritic, martensitic, duplex (ferritic - austenitic) stainless steel cold rolled coils and hot rolled coil. 

Stainless steel plate: a cold rolled and hot-rolled stainless steel plates of the points, its surface shiny, matte, matte surface, commonly known as stainless steel, with steel strip plates, BA plates It may also according to customer requirements other light color coated sheet.. the specifications are: 1m * 1m 1m * 2m 1.22m * 2.44m 1.5m * 3m 1.5m * 6m, if the customer demand, we can reduce the dimensions of the customer another may be doing some drawing boards, skid plates. plate.

Process for bright annealing of stainless steel object

1 ) Elimination of hardening obtain satisfactory microstructure
Bright annealing furnace is mainly used for heat treatment of stainless steel coils finished in a protective atmosphere . When using the performance requirements are not the same time, bright annealed microstructure after the request is different , bright heat treatment process is also different.
A typical 300 series austenitic stainless steel heat treatment process is the solution treatment . In the heating process, to carbide dissolved in austenite , and heated to 1050 ~ 1150 ℃, appropriate heat for a short time , all dissolved carbides in the austenite , and then rapidly cooled to below 350 ℃, i.e. a supersaturated solid solution to obtain a uniform unidirectional austenite. The key to this is the rapid cooling of the heat 430 stainless steel coil , the cooling rate required to reach 55 ℃ / s, fast after solution by re- precipitation of carbides temperature zone (550 ~ 850 ℃). Holding time to be as short as possible , otherwise the coarse grains , the impact of surface finish.

304 stainless steel coil large lifting cranes

Vertical bright heat treatment furnace body about 45m high . Vertical furnace equipment for operation monitoring , to provide adequate means of communication instruments . Vertical structure also brings some stainless steel sheet coil, such as cleaning and solve bad fall in the steel surface is waste . A famous American steel cold rolling mill on these issues has been plagued by increasing cleaning frequency had resolved .
Stove body height of about 45m, muffle cover about 16m, life about four years . When muffle cover replaced, drawn from the roof , lifting height is estimated at around 65m. Require appropriate operating cranes and operating space . In this regard , in the plant design, layout must be fully considered.
For the vertical furnace plant was supporting local high tower . In order to ensure uniform tension strip , 304 stainless steel coil, runs smoothly , high precision equipment installation . Thus the basis of differential settlement amount to be strictly controlled. Routine maintenance and overhaul plant height required large lifting cranes, elevators, fire , forced ventilation and other measures should be supporting in place.
