[0012] The 5754 sound barrier aluminum alloy belongs to the aluminum-magnesium alloy, which is a typical alloy in the 5 series. It has the advantages of medium and high strength, light weight, good formability, corrosion resistance, and sound absorption, and is more and more widely used in high-speed trains. , urban rail transit, automobiles and other means of transportation and their ancillary facilities.
[0013] The 5754 sound barrier aluminum alloy is casted to obtain billets, firstly hot-rolled billets, and then cold-rolled four times to make strips and coils. The strips and coils are annealed in H24 state and supplied to customers as finished products. The method of high-temperature rapid sampling of the 5754 sound barrier aluminum alloy plate, strip and coil after annealing the finished product in the H24 state includes the following steps: the first step: the plate and strip coil is installed on the recoiling unit to clean the coil surface; the second step: The str...

[0019] 300311 aluminum alloy belongs to aluminum-manganese alloy. Since the customer needs H14 state 0.71mm thick strip and coil, it needs to be annealed to O state first, and then cold-rolled with 25% reduction to supply the finished product to the customer.
[0020] The 300311 aluminum alloy is casted to obtain a billet, which is first hot-rolled and then cold-rolled four times to make a strip coil. It needs to be annealed to the O state first, and then cold-rolled with a reduction of 25%. Provide customers with finished products. The method of rapid sampling at high temperature after the 300311 aluminum alloy plate, strip and coil has been annealed in the H14 state includes the following steps: the first step: the plate and strip coil is installed on the recoiling unit to clean the coil surface; the second step: the recoiling unit Roll the upper strip coil to the outer ring of the coil and stop when it is 28mm-32mm away from the sleeve of the rewinding unit. Use a cutting m...

[0025] Brass is an alloy of copper and zinc. The simplest brass is a copper-zinc binary alloy, called simple brass or ordinary brass. Brass with different mechanical properties can be obtained by changing the content of zinc in brass. The higher the zinc content in brass, the higher its strength and slightly lower plasticity. C26000-O state is the most widely used variety in brass. It has excellent plasticity, high strength, good machinability, welding, and corrosion resistance. It is an indispensable deep-drawing material in industry and can be used to make heat exchangers, paper-making tubes, machinery, electronic parts, cartridge cases, etc. .
[0026] C26000 brass alloy strips and coils are casted to obtain billets, hot-rolled to obtain hot-rolled billets, then annealed for hot-rolled billets, and then made into strips and coils after three passes of cold rolling. Finished products are annealed and supplied to customers as finished products. C26000 brass alloy pla...
