Abstract

The invention provides steel for card clothing. The steel is prepared from the following components in percentage by mass: 0.75 to 0.85 percent of C, 0.10 to 0.50 percent of Si, 0.30 to 0.90 percent of Mn, 0.20 to 0.50 percent of Cr, smaller than 0.02 percent of P, smaller than 0.01 percent of S, 0.04 to 0.20 percent of V, 0.015 to 0.060 percent of Nb, 0 to 0.50 percent of Ni, 0 to 0.50 percent of Mo, 0 to 0.40 percent of Cu, and the balance being inevitable impurities. According to the steel disclosed by the invention, by adopting a mode of reasonably adding Nb and V, produced card clothing undergoing quenching-tempering heat treatment has crystal particle size of over 12 grades and hardness of over 800HV0.2 can be guaranteed while the steel has good cold processing forming performance, the wear resistance of products is remarkably improved, and the service life is also greatly prolonged.

Description

A kind of pin cloth steel
Technical field
The invention belongs to metallic card clothing processing technique field, be specifically related to a kind of pin cloth steel.
Background technology
Pin cloth steel is first to pin cloth finished product from hot rolling dish, need to through cold-drawn, intermediate heat-treatment, cold rolling, die-cut and quenching+tempering operation, thus require it to have cold-formed function admirable, Technology for Heating Processing response is good, finished product pin waring of cloth high and is not susceptible to the feature fractureed.For many years, domestic Zhen Bu manufacturing enterprise mostly selects the steel consistent with Overseas Clothing steel product ingredient, but is difficult to be fully achieved international most advanced level in terms of production and application effect.
Micro-alloying technology refers to carbide, the nitride forming elements such as Nb, V, Ti of adding trace in steel, under the effect of thermal cycle or strain, by dissolving and the control of precipitation process of C, N compound, making the mechanical property of ferrous materials, processability and serviceability be significantly improved, this has obtained application widely in Hi-Stren steel.And recent study result shows, high-carbon steel uses micro-alloying technology, the performance improving steel also can be produced positive effect.Traditional pin cloth steel mainly uses W and V alloy in terms of alloying, but the effect of W is not particularly suited for pin cloth product.
Summary of the invention
The technical problem to be solved is to provide a kind of pin cloth steel, these steel are while having good cold-formed performance, the pin cloth produced can be made again to have ultra-fine metallographic structure and high rigidity, significantly improve wearability, substantially prolongs service life.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of pin cloth steel, it includes the following ingredients formed by mass percentage:
C:0.75 ~ 0.85%, Si:0.10 ~ 0.50%, Mn:0.30 ~ 0.90%, Cr:0.20 ~ 0.50%, P: < 0.02%, S: < 0.01%, V:0.04 ~ 0.20%, Nb:0.015 ~ 0.060%, Ni:0 ~ 0.50%, Mo:0 ~ 0.50%, Cu:0 ~ 0.40%, remaining is Fe and inevitable impurity.
As preferably, above-mentioned pin cloth ladle includes the following ingredients formed by mass percentage:
C:0.75 ~ 0.85 %, Si:0.20 ~ 0.30%, Mn:0.50 ~ 0.70%, Cr:0.20 ~ 0.40%, P: < 0.02%, S: < 0.01%, V:0.05 ~ 0.15%, Nb:0.020 ~ 0.040%, Ni:0 ~ 0.50%, Mo:0 ~ 0.50%, Cu:0 ~ 0.40%, remaining is Fe and inevitable impurity.
The invention has the beneficial effects as follows: the present invention uses the mode rationally adding Nb and V, and Nb can make the eutectoid carbon content of steel raise, thus increase the carbon content in martensite after quenching, and Nb also makes cementite be prone to nodularization, meets pre-processing requirements；V both can form the V (C that size is tiny, N), also can be partially into cementite, improve alloyed cementite stability and reduce its size, Austenite Grain Growth is effectively stoped when heat treatment heats, so that while steel have good cold-formed performance, crystallite dimension (GB/T 6394-2002) and the hardness of more than HV800 of more than 12 grades is possessed after can ensure that again the quenched tempering heat treatment of pin cloth produced, significantly improve the wearability of product, also substantially prolongs service life.
