Abstract

The present invention discloses a backing material for a double metal composite saw blade, and a preparation method thereof. The backing material is manufactured from waste iron and steel, chrome, nickel, copper, molybdenum, niobium, vanadium, tungsten and other raw materials by carrying out smelting, forging, hot rolling, acid washing, spheroidization annealing, cold rolling and other steps. The backing material can meet welding requirements of the double metal saw blade, wherein the double metal saw blade produced from the backing material has characteristics of good quality and long service life.

Description

technical field [0001] The invention relates to a steel strip and a preparation method thereof. Specifically, it is a back material for producing bimetal composite saw blades and a preparation method thereof. Background technique [0002] It is known in the metallurgical industry that the bimetallic composite saw blade is made of two materials, the back material and the tooth material. The back material composition is mainly made of scrap iron and steel, chromium, nickel, copper and molybdenum, and elements are adjusted during the smelting process so that the composition also contains carbon, silicon, manganese, phosphorus and sulfur elements. Since the back material is only composed of the above-mentioned elements, it cannot meet the welding requirements of the bimetallic saw blade, so that the quality of the produced bimetallic saw blade is poor and the service life is short. Contents of the invention [0003] The problem to be solved by the present invention is to pro...
