The characteristic of alloy steel casting is similar to that of Carbon Steel Casting and cast steel containing alloy elements such as manganese, chromium, and copper is a cast alloy steel. China Alloy Steel Precision Casting is also called lost wax casting, or China Alloy Steel Investment Casting . Casting products are precise, complex, and close to the final shape of the parts, which can be used without processing or with little processing, so It is an advanced technology.
In wax pattern process,we mix stearic acid and paraffin wax in wax pattern making,as you know,it is better than polyethylene,and the wax deformation is small.
In
shell making,we adopt automatic sand-covering production line, which was
invented under the guidance of our general manager.The indoor temperature was
controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more
stable,the internal tissues much more well-proportioned.
In
shell hardening process,we use aluminium chloride to harden the shell.This can
make the shell so hard that it can`t be distorted,at the same time the bug
which the casting may have will be decreased.If there are letters or numbers in
it,they will be much clearer.
In
dewaxing process,about 95% of the castings suppliers adopt the original water dewaxing
technics,but we using the advanced steam dewaxing technics,which we are very
proud of.This can effectively avoid the air-hole and sand-hole,making the
casting look much nicer.
In
smelt process,we use middle frequency furnace,avoiding the emergence of the
oxide; in molten steel control part,we use Germany-imported direct reading spectrometer
machine,assuring its quality before the molten steel out of the furnace.During
this process we use ERP production and management software to get the feedback
information.
In
shell-knock out process,we have special machines,which can decrease the hitting
and knocking, easily made by manual shell knocking out.
In shot-blasting
process,we have crawler-type and hanging shot-blasting machine,with steel shot
0.5-0.8,making the products smooth.Of course,if the customer wants it look much
nicer,we also can carry out sand-blast treatment.
In
heat treatment process,we use electric furnace,and adopt double-temperature
control in order to heat the products equally.As a result, the products will
have great metallurgical structure.
Our
tolerance can reach at the grade of 5-7 according to our country`s tolerance
standard.
In machining process,we have 12 CNC machining centers
and some other machines, so we can make further machining if the customers need.
Products in alloy steel cast factory divide into Forklift Parts Investment Casting, Agricultural Machinery Parts Investment Casting, Petroleum Parts Investment Casting, and Chemical Parts Investment Casting.

Working Principles:Â 
  Raw material is placed into the feeding hopper, which leads to the
hammer chamber where the material enters from the top and is beaten and crushed (hammered)
by high speed rotating blades. Under centrifugal force the material is processed quickly due to
continuous squeezing, crushing, and beating, by the hammer mill blades. Under rotor centrifugal
force, fan suction force, and gravity crushed material and air is discharged through the holes in
the 180 degree screen on the bottom while those that cannot get through will repeat the process
until they are small enough to pass through the screen into the lower body of the hammer mill.
Features:
1. It is used for grinding raw materials by large and medium livestock and aqua feed mills. It can also be used for grass and pharmacy fine grinding. The granular raw materials, such as corn, sorghum, wheat, beans, etc can be grinded;
2. It is derived from tear circle type hammer mill and efficiency can be improved by 45%-90% comparing to universal hammer mill;
3. It can produce qualified aqua feed under full load with 0.8\1 screen and reduce jam significantly. Both coarse and fine grinding can be realized without changing screens;
4. The right aspiration can make materials go through screen quickly, reduce temperature of grinding chamber and increase output effectively.
 Multifunctional wood hammer mills are our company specializing in the production; the machine uses hammer hit screens to get the goods. According to the proportion of materials and output to choose type of machine.
  Multifunctional Wood Hammer Mill is our finalize the design products , it is a best machine to crush kinds of straw , weeds , PVC foam board, rubber, plastic etc. So could be called straw hammer mill, wood hammer mill, rice husk hammer mill, cotton stalk hammer mill, PVC hammer mill.

Advantage of Hammer Mill
Â
1.Can design the vertical or horizontal hopper for your specific requirement.
2.Rotor structure. It ensures no dead corner inside and makes the finish products evenly.
3. Multifunctional. hammer mill can handles fertilizer,animal food and biomass material Security lock. To ensure the doors will not open during operation.
4.The hammer mill usually works with cyclone; the cyclone can filter out the dust from finished products.Â
5.A variable frequency drive could be installed on the belt conveyor to hammer mill, so you can adjust the right speed for the material.
