heat select
3.Light quality indefinite type pour material is it insulate against heat of good performance to have , heat conduction coefficient little , energy-conserving result remarkable , the intensity is high , the line changes littly, various kinds of stove kiln ideal inside lining , adiabatic material, please according to select different materials for use while being different kinds of, it is easy to economize the kiln cost.
5.As a result of function admirable, service is considerate, force product was won in the client east taller famous spend and beautiful praise degree, be out of job in metallurgy among them market of machine of roller path decelerate has first place of rate house whole nation, be in especially steely industry 2 meters of above are large on the form a complete set that cold, heat joins press hard against each other, by home each big steely company labels the line that replaces an entrance to select a product, win " transmission industry small giant " beautiful praise.
7.How to control the viscosity of upgraded chips, how to select right spinneret and how to set the proper parameters of drawing & heat setting have been systematically investigated, and a successful solution to produce high performance polyester industrial yarn with the EASL(4.0cN/dtex) around 5% and hot air shrinkage (177℃,1 min) from 4% to 5% has been reached.
8.According to these, the paper put forward some countermeasures: select low carbon steel or low metal alloy steel with lower intensity, like 20R steel; ② while welding, adopt strict craft measures with lower welding heat to input; ③ after jointing, proceed the whole hot dissolving on time; ④ control each welding joint with hardness HB≤185; ⑤ add 0. 25% water into the liquid ammonia as decay eclipse; ⑥ enhance checking in operation, repairing equipment in time through regular interior and exterior checking.
