Pumps thirty-one Boom http://www.cnbggs.com

My company's Boom completely Angang 45Mn2, (Angang 45Mn2 and Qingzhou Lu Xing, Jiangxi Hongdu, Jilin steel 45Mn2 comparison: uneven small molecular structure steel, silicon, sulfur seriously overweight, the content of silicon in the 44- 55 per thousand, brittle, partial arm in serious condition, heat treatment fitness is not good, easy to burst, the price per ton lower than Angang, Baosteel 700-1300 yuan.) equipment from Germany FLE Super Audio heat treatment equipment, high case hardness , Rockwell hardness greater than 70, even hardened layer, it is possible to overcome the soft band phenomenon, heat electricity at around 60-70 dollars each. Some small manufacturers use IF heat treatment, hardened layer is uneven, a wave condition, hardness about 50 Rockwell hardness, soft belt is serious, heat treatment costs between 12-15 dollars. Our company Boom stringent quality control, welding expect from the next to the heat treatment, commitment to quality and packaging are in a domestic first-class level of our company and the quality of abrasion resistant pipes and other manufacturers of comparison: a base material completely Angang 45Mn2. 2 flange using 50mm high wear, abrasion sets using GCr15 "7" alloy sets in the country is unique. Other manufacturers flange wear at most 45mm high, set general processing or no wear sleeve with its director 45Mn2 carburizing. 3 I wear tube wall in Rockwell hardness 70-75, are any of the remaining one can not achieve. 4 Length error of less than 1.5mm, concentricity error 0.2mm, parallelism error 2, the hardened layer thickness of 1.8mm-2.2mm. Rockwell hardness greater than 70. Tube and wear sleeve middle gap is less than 0.2mm. This is the other manufacturers unattainable
