Q:The working principle of steel punching machine
2, two dimensional coordinates can be stopped at the same time manual conditioning, high and low speed movement, relative zero programming, automatic back zero, two axis linkage;3 directly input digital programming, use panel or remote stop control4, stable quality, reliable performance, cumbersome operation, safe and efficient.
Q:The steel structure material can do
Yes, if you are easy to do, you can
Q:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
Wear zinc coating first, otherwise it is easy to form inclusion and other defects, and damage the strength of matrix.
Q:What is the hot dip galvanized steel, production process?
The steel piece after being cleaned is dipped into the molten zinc liquid at about 445 DEG C so that the zinc coating is adhered on the surface of the steel member so as to prevent corrosion. Hot galvanizing process: finished acid washing - plating bath - drying - hanging - cooling - passivation - Cleaning - polishing - Inspection - finished products
Q:What is the cold drawn steel material? Why did it break?
20 steel 45 steel Q235B a little more material, no annealing treatment
Q:The anti-theft lock in the steel compression spring is what?
The development trend of suspension spring steel is to reduce carbon content, reduce decarburization tendency, and increase the flexibility and anti attenuation performance of plastic forming.
Q:4 x6 1.5 square meters thick, how much money
1, the steel prices generally calculated in tons. To see you say the steel is hot dip galvanized or black material.2, hot galvanized general 4500/ tons,3, black wood generally in 3800/ tons.That is 4.5 yuan /kg and 3.8 yuan /kg. Forget it. You say this kind of steel is 2.355kg per meter,
Q:Glass partition, square box outsourcing 1mm thick stainless steel, glass middle is how to set the quota
In this case, a metal frame must be used to hold the glass and then bolt it into the wall!
Q:As for steel structure steel, how appropriate
Column: 200*200*8 rectangular tube as column, beam (main beam) is 300*300*12, secondary beam is 150*150*8@1500 evenly distributed. Roof beam 150*150*8 herringbone roof truss.
Q:The difference between cold and hot galvanized steel hollow where
Hot rolling process is: the ingot directly into square tube, and then galvanized, also known as seamless pipe.Usually than cold-rolled steel hot-rolled square steel prices high.
