Abstract
The invention provides a blower steel ball to meet the current market demand for high strength steel ball in China and reduce the production cost for the blower manufactures in China. The steel ball is made of high quality GCr15 bearing steel by a heat treatment process. The heat treating process is as follows: raw material-heat impact-spheroidizing annealing-buffing-soft grinding-quenching and tempering-hard grinding-intermediate appearance-stabilizing tempering-primary grinding-vortex flow-fine grinding-packing and putting into storage; the value of load for grinding is 1.4 to 2 times the national standard and reaches the technical standard of the same class products, thereby realizing the aim of the invention.
Description
Technical field
The present invention relates to a kind of steel ball, particularly a kind of blast engine steel ball that is specifically designed in the blower.
Background technique
Use bearing to require very high in blower in the market and the wind-driven generator because of its Crush Strength to bearing steel ball, so till the present, steel ball all adopts the bearing steel ball of external import in blower and the wind-driven generator, and its Crush Strength is generally about 2 times of domestic steel ball; But the cost of the bearing steel ball of external import is than higher, and the cost of production of the manufacturing enterprise that causes is also than higher.
Therefore, need a kind of blast engine steel ball especially, in order to filling the domestic gaps, satisfy now the Domestic market, reduced the cost of production of domestic blower producer simultaneously for the needs of high strength steel ball.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of blast engine steel ball, satisfies now the Domestic market for the needs of high strength steel ball, has reduced the cost of production of domestic blower producer simultaneously.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of blast engine steel ball is characterized in that, it is made up of high quality GCr15 Bearing Steel.
Described blast engine steel ball adopts heat treatment process, and its technological process is as follows:
Raw material-heat dashes-and spheroidizing annealing-tarry matter-buffing-quench, tempering-hard grind-intermediate appearance-stable tempering-early grind-eddy current-lappingout-packing put in storage.
The heating-up temperature of described quenching, proparea temperature are 860 ± 5 ℃, and heating back zone temperature is 850 ± 5 ℃, and holding time is 35 ' 04 ", the handwheel position of hardening furnace is 5 grades, ball load is 8.5Kg/ time.
The tempering temperature of described tempering is 160 ± 5 ℃, and temper time is 88 ' 48 ", the handwheel position of tempering furnace is 7 grades.
The temperature of described double tempering is 180 ℃, and the time is 3 hours.
The tempering temperature of described stable tempering is 160 ± 5 ℃, and temper time is 3 hours.
Blast engine steel ball of the present invention adopts heat treatment process, and its crushing load value is 1.4～2 times of NBS, reaches the technical standard of external like product, has realized purpose of the present invention.
