Our company is a professional company. Company mainly engaged in the production of castings of elevator parts, machinery parts, Weights. Corporation has a number of professional production factory, the powerful production capacity, will produce various types of ductile iron, gray cast iron, cast iron, cast steel, cast 15000 tons. Company technology capacity strong, quality management strictly, quality means complete, on user orders by requirements of quality, number, date has powerful of production and quality guarantee capacity, I company to by pig iron, coke carbon raw materials base; and quality excellent, can full meet production using, years, I company to both at home and abroad supply and the export of casting due to emphasizes quality, supply rates, by user of consistent praise, welcomes members user to I company to guide and chat orders!

Casting the purpose of tempering is as follows:

1. reduce brittleness, eliminating or reducing stress, there is a chamfer steel after quenching stress and brittleness, if not to temper tends to cause deformations in the steel and even cracking.

2. to obtain the required mechanical properties of the workpiece and workpieces quenched hardness and brittleness in order to meet the different requirements of various artifacts, can be adjusted by appropriate tempering tie to hardness, decreases brittleness and toughness needed to get the plastic.

3. stable size

4. annealing to soften some of the alloy steel, hardened (or fire) is often used after tempering, make appropriate aggregation of carbide in steel, to reduce the hardness to facilitate cutting.

5 machine tool castings production also needs normalizing

Normalizing is the steel is heated above the critical temperature 30-50 ℃, holding the appropriate time, in still air cooling of the heat treatment process is called normalizing. Normalized fine-grained structure is the primary purpose, improving performance, get close to the equilibrium of the organization.

Normalizing and annealing process, the major difference is normalizing cooling slightly faster, so the normalizing of the short production cycle. Annealing and normalizing the same performance requirements can reach parts, used the fire as possible. In most, mild steel billet is used for normalizing. Alloy billet annealing is used frequently in General, if the normalized, cooling is fast, its high hardness after normalizing, is not conducive to cutting.

A qualified product, must be strictly through the various links, each link on small differences, and ultimately affects the quality of the product. Our company specializes in manufacturing all kinds of cast iron plate, cast iron platform, face plate, faceplate, measuring tools, attentive to every detail, carefully to every product

Gray cast iron Mainly used for machine parts and blanks, precision castings, can also be used directly as parts of the machine. Casting machinery products accounted for a large proportion, such as tractors, casting weight around the weight of 50~ 70%, 40~ 70% of agricultural machinery, machine tools, internal combustion engines up to 70~ in 90%. In all types of castings, castings of machinery most varieties, the most complex shapes, had the greatest amount, accounting for about 60% of casting production. Followed by metallurgy moulds and engineering pipeline.

Non-machined surface and appearance of casting for casting commercial influential, they include:

⑴ the smoothness of the surface (rose boxes, depression and mortar);

B surface or cavity cleanliness (sand, sticky ' paint ');

⑶ flatness deviation (non-machined surface uneven);

D surface roughness;

⑸ sharpness (lug, umbilical and other structural units of the clear-cut, assessed with the naked eye). Machine casting on disappeared die of requirements: coated die ⑴: paint requirements: used water base graphite paint, its Baume degrees for 60-70 Zhijian, brushing Shi in greenhouse within, drying Qian is strictly prohibited move, to prevent deformation b brush coated requirements: paint mixing uniform, brush coated Shi rigorous white. c coating drying: paint for dry Hou to has enough of strength, in 50-60 ℃ of drying 24h.

Our products are divided into two series:

(1) heavy machinery products: various models of the new type single or double column vertical lathe, test pads box, designed and manufactured according to customer needs. heavy, large, medium size CNC machine tool, vertical lathes, machine tools, metal bed, non-standard casting machine tool bed castings, beam gantry milling machine, cast iron mechanical slide unit; Boring machine bed castings, bearing cast, fencing wire base, with heavy iron, nodular casting, the road squats, weight iron and other products of the processing system design and installation.
(2) machine measuring: cast iron flat platform, Assembly flat, carved line flat, cast iron table, cast iron set disc, fitter underlined platform, test flat, welding flat, riveting welding flat, marble flat, machine table flat feet, party box, aluminum magnesium flat feet, granite flat, granite measuring, flat feet, square, feet,, machine pad iron (adjustment pad iron, earthquake pad iron)

Machine produced by our company has the advanced design, attractive appearance, reliable performance, accuracy and stability, operation is simple and advantages of easy maintenance, we will be quality products, attentive after-sales service return to our old and new customers, and adhere to the credibility of the first, customer supreme principle, contracts, keep promises, fully implement three guarantees, follow-up service.
