Abstract
The present invention discloses a saw blade which is made of an old waste steel rail and is used for cutting granite. An old waste steel rail in a railway is used as raw materials. A rail head, a rail web and a rail bottom of the old waste steel rail which is not used in the railway are respectively cut into section blanks, then, the section blanks are conveyed into a furnace to be heated so as to form red blanks, and the saw blade for cutting granite can be made after process steps, such as rolling operation, wind quenching heat treatment, finishing operation, etc., are carried out. The mechanical property of the saw blade is the same as the mechanical property of an imported product, and the present invention has the advantages of stable quality, low manufacture cost, stable material sources, resource saving of changing waste into valuables, etc. Compared with the imported product, the present invention has the advantage of high performance-price ratio. The present invention has strong market competing capability.
Description
Technical field
The present invention relates to a kind of method of making the saw blade steel band of cutting granite, particularly the method for the cutting granite saw blade steel band of making of waste and old steel rail.
Background technology
Granite is a kind of building and ornament materials, it is the Modern Family room, the office space, the supermarket, shop is in order to fitting-up and play one of essential articles for use of the effect of beautifying the environment, fast development along with Chinese national economy, the significantly raising of people's living standard, people have brought the strong request that site surroundings such as room and office are beautified to the variation of the pursuit of fairly comfortable life, no matter the favor that granite gets people because of the advantage of the lithotome that it had is outstanding is decoration granite or the office that family room uses, the decoration granite that the place, shop is used all is growing on and on; This wilderness demand to decoration granite, brought demand to stone machining equipment, the saw blade steel band is a kind of important instrument in stone machining equipment, in the cutting of granite, play an important role, the saw blade steel band of the cutting granite of modern technologies is mainly the sand saw, the sand saw blade steel band is quite a kind of grinding tool in fact, it is stretched on the framework of saw, in cutting process, be on the waste stone of granite, to do powerful the reciprocating motion by the saw blade steel band, the mortar leader tape that hard steel sand is modulated into gone into cut surface, grind saw kerf and finish cutting, simultaneously its consumption that oneself also is worn.So the saw blade steel band of cutting granite must have high strength, high-wearing feature and enough toughness, for the mechanical performance that obtains to require, it should have corresponding chemical analysis, obtains the metallographic structure of requirement through heat treatment.The saw blade steel band of cutting granite is as a kind of easily-consumed products, demand is bigger, and the saw blade steel band of cutting granite is because it is to cast blank with the special steel grade of smelting to make, and mostly be import greatly, cause cost higher, cause the processing cost of granite higher, the price of stone material is risen, influenced the utilization of granite; And develop the saw blade steel band of cutting granite voluntarily in order to reduce cost, at first need the smelting that solves and the problem of strip plate, but for various reasons, domestic do not have a proprietary material, if painstakingly go development, will spend more time, manpower and financial resources, cause cost to raise equally, make the product of working it out lack competitiveness.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide that a kind of material source is stable, product properties and imported product quite and the low saw blade steel band of cost of manufacture with the cutting granite of waste and old steel rail making.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method of making cutting granite saw blade steel band, it is to be raw material with the railway waste and old steel rail, waste and old steel rail is disassembled by rail head, the web of the rail, the flange of rail, and the section of being cut into base on demand then is made by following operation again:
(a) blank heating;
(b) rolling;
(c) the wind heat treatment of quenching;
(d) finishing.
The invention has the beneficial effects as follows, owing to adopted with the blank of the retired waste and old steel rail of railway as the saw blade steel band of cutting granite, the one, waste and old steel rail institute carbon containing, manganese, chromium suit, after heat treatment has very high intensity and enough toughness, not only wear-resisting but also anti-Zhang Naizhen is arranged during use, its product properties and imported product are suitable, because of it is twice laid, both helped environmental protection, the finished product price is reduced greatly; The 2nd, rail is the product of national strict implementation quality control, and its chemical analysis physicochemical property is highly stable, makes the steady quality of the saw blade steel band that waste and old steel rail makes obtain assurance; The 3rd, annual country all will be from railway a large amount of waste and old steel rail of backing off, and this provides stable material source for the saw blade steel band; The 4th, directly use waste and old steel rail as blank, the blank that is rolled into again than the saw blade strip material of special smelting on price is much lower, helps reducing manufacturing cost, improves cost performance, enhances one's market competitiveness.
The specific embodiment
The present invention makes the method for the saw blade steel band of cutting granite of waste and old steel rail, it is to be raw material with the railway waste and old steel rail, waste and old steel rail retired on the railway is collected, and the rail head of waste and old steel rail and the junction of the web of the rail, the web of the rail and the flange of rail cut the section of being cut into base on demand again with semi auto cutting machine; By production process the section base is put into then and be heated into red base in the stove, and, again the finishing after wind is quenched heat treatment of saw blade steel band semi-finished product promptly be can be made into the saw blade steel band through mill milling saw blade steel band semi-finished product into strips.
Claims (1)
1, a kind of method of making cutting granite saw blade steel band is characterized in that: it is to be raw material with the railway waste and old steel rail, and waste and old steel rail is disassembled by rail head, the web of the rail, the flange of rail, and the section of being cut into base on demand then is made by following operation again:
(a) blank heating;
(b) rolling;
(c) the wind heat treatment of quenching;
(d) finishing.
