A, the new process:

At the beginning of 1.2001 on the well type annealing furnace microcomputer control, hydrogen protection, semi-finished products and finished products round wire and billet all monitoring, improve quality, uniform hardness, reduce differential, no oxidation and decarburization. Colour and lustre is uniform, is silvery white, close to the bright annealing.

2.2002 years and the high frequency annealing process, the main features:

A. the sanlian mill rolling billet without well type annealing, straight tooth shape, reduce burr, billet article general control in 240-270 hv hardness;

B. high frequency annealing after blunt teeth, solve the colour and lustre, high frequency at the same time after annealing billet article base hardness uniformity, stability, poor not more than 15 point hardness.

C. due to the high frequency annealing before quenching effect, make the body into a straight line, there is no bend, uniformity and stability of quenching.

Second, the new products:

In order to adapt to the carding clothing and carding equipment needs, we also develop AC20 series cylinder clothing and AD4050J arc Angle changed tooth doffer card clothing.

The newly developed arc Angle changed doffer card clothing, the specification AD4050J x 02190, the main features are:

A. tooth profile is unique, the tooth of the chick, lower using common doffer shape, can be combined according to tooth profile, the upper working Angle of 40 °, the anterior horn of 50 °, the second half of the working Angle of 60 °, rake Angle of 30 °.

B. replace AD5030 doffer card clothing, and AC2030, AC2035 supporting, solve the lapped difficult.

C. composite tooth profile, upper part of the small working Angle increase the rate of transfer of doffer.

D. big pitch, a big gap to solve the problem of the drainage of the high-speed airflow.

E. is mainly suitable for carding and high production carding machine at a high speed. Such as: Swiss rieter C4 carding, doffer phi 500 mm roller, and ordinary for phi 700 mm, lapped difficulties, and AD4050J alternatives.

4. This year the latest new products, a high wear light clothing.

Three, this year's launch of the latest products - ecru resistance high shining metal card clothing

Features:

1. Using H2 quenching hardness of 850-920 hv, the whole plate of not more than 20 hv, can improve the service life.

2. The wire surface for silver light, break the black or blue, surface without scale (the actual past blue and black are all scale). Increase the degree of finish, reduce fiber.

3. Raw materials using imported from Japan 82 b and Belgium imports of finished steel wire production.

Finally thank the conference organizers and co-organizers create opportunities for us. On behalf of the company general manager zhang invite you to our shanxi xinhui clothing co., LTD., to set away. For the prosperity of our country spinning combed cotton industry, and seek common development.
