Many years mature foundry experience for shaker hearth furnace plates, expecially the mature gating system so that the cast defects are avoided like cast porosity, shrinkage,blowholes. The outside quality and inside quality of the hearth plates work very well and last longer service life. The shaker hearth furnace plates made by HEXIN Machinery, features high durability, tensile strength, corrosion resistance and high performance. 

 Qingdao Hexin Machinery is professional with producing blast turbines for the shot blasting machine. The blast turbine of the shot blasting machine is the key component of the shot blasting machine, which is also called shot blasting abrator wheel, blasting impeller, or blasting wheels. Shot blast turbine consists of blade holder,turbines, control cages and blasting blades. Blasting blades can be straight, curved or trapezoid. and its quality and service life directly depend on the blades.  Because the blade is in a high-speed rotating impeller when it is working, it has to bear the wear of the steel shot abrasive and the erosion wear of the high-speed shot flow.  Under these two forms of wear, whether the blade is easy to use depends on the material of the blade. After high-chromium wear-resistant cast iron is applied to the blade of the shot blasting machine, the average life of the blade can be more than 400h.  Chilling the blade surface with cold iron not only realizes the sequ

 Shot blasting machine wear resistant liners and brackets are produced by resin sand casting, or lost wax investment casting. Qingdao Hexin Machinery is professional in producing wear resistant liners, and we use special chrome cast iron or manganese steels. The chrome white cast iron, generally refers to chrome white cast iron containing cementite carbide.  Since the carbon content of the alloy and the solidification rate of the casting have a great effect on the critical chromium concentration affecting the structural transformation of the carbide,  it is not possible to define the type of chromium white cast iron according to the chromium content. Under industrial production conditions, the solidification rate far exceeds the equilibrium transformation rate, plus the influence of carbon, silicon, and manganese in cast iron. In addition to M3c-type carbides,  M7C3-type carbides also exist in white cast iron containing less than chromium. Moreover, with the increase of chromium conte

 Qingdao Hexin Machinery is professional in producing blast wheel control cage . The blast wheel control cage is one of the core component of the shot blasting machine, which is to control the direction of the shot blasting through the control cage. The function of the control cage is to control the direction of the projectile, send the projectile to the blade correctly according to certain requirements, and the divergent flow of the projectile will become regular.  By adjusting the opening position of the directional sleeve reasonably, the shot blasting effect can be greatly improved. . Through the cooperation with the shot separation wheel, the steel shot reasonably enters the blade projection area, and then is projected to the workpiece surface at high speed. Universal shot blasting machines such as crawler type shot blasting machine, hook type shot blasting machine, rotary type shot blasting machine, etc. do not need to adjust the directional sleeve frequently. The adjustment of t

 Qingdao Hexin Machinery is professional with casting various wear resistant parts for most shot blast machines. The wear resistant castings are generally made from special irons and manganese steels. Typical spare parts like shot blast turbines, blades, blade holders, contro cages, wear resistant side liners, brackets, etc.,

  radiant coils for cracker by Qingdao Hexin Machinery Co., Ltd. The petrochemical cracking tube is suitable for cracking furnace (cracking furnace), which refers to the equipment used to carry out the cracking reaction of hydrocarbons. The requirement to the cracking furnace is: (1) the reactant can be quickly heated to 700～90CTC to ensure the equilibrium yield of ethylene, and heat supply and heat transfer need to be guaranteed; (2) the medium residence time is short, reducing the coke in the cracking process (3) suitable high temperature resistant materials. Due to the differences in the raw materials used for cracking and the method of providing the heat required for cracking, different types of cracking furnaces are used, such as regenerative cracking furnaces, sand furnaces and tubular cracking furnaces. The most widely used and the most mature technology is the tubular cracking furnace. In the past, the cracking tube generally used HK-40 alloy steel containing 20% ​​nickel and
