Problems solved by technology

However, production must be restricted by market orders. Small batches and multiple varieties are a major feature and trend of production organizations. Because one change of varieties requires one reloading of straightening rollers, the pursuit of excessively high "one-time use" Life" does not conform to the actual production, so the above-mentioned patented products have not been popularized and used in my country's section steel straightening industry

Embodiment 1

[0018] Using micro-carbon chromium or low-carbon chromium, 99 nickel plate, electrolytic manganese, 75 silicon, 50% molybdenum concentrate and pig iron as raw materials, the raw materials are put into the furnace and refined at 1480~1500°C to obtain a molten alloy solution. It is poured into a mold at room temperature, and the straightening roller is obtained after cooling. The weight ratio of the components in the final straightening roller is: 1.2% chromium, 1.3% nickel, 0.2% molybdenum, 0.4% copper, 3.3% carbon, Silicon 0.6%, manganese 0.3%, sulfur and phosphorus content are all less than 0.01%, and the rest is iron.

[0019] Straightening rollers are divided into three structures from the skin to the inside: white mouth, horse steel and gray mouth without boundaries.

Embodiment 2

[0021] Using medium-carbon chromium, 99 nickel plate, low-carbon manganese, 75 silicon, 50% molybdenum concentrate and pig iron as raw materials, put the raw materials into the furnace for refining at 1480~1500°C to obtain a molten alloy solution, which is heated at room temperature Cast in the mold under the environment, and get the straightening roller after cooling. The weight ratio of the components in the final straightening roller is: 1.35% chromium, 1.4% nickel, 0.25% molybdenum, 0.5% copper, 3.5% carbon, and 0.7% silicon , manganese 0.4%, sulfur and phosphorus content are all less than 0.01%, and the rest is iron.

[0022] Straightening rollers are divided into three structures from the skin to the inside: white mouth, horse steel and gray mouth without boundaries.

Embodiment 3

[0024] Using high-carbon chromium, 99 nickel plate, high-carbon manganese, 75 silicon, 50% molybdenum concentrate and scrap iron and steel as raw materials, the raw materials are put into the furnace and refined at 1480~1500°C to obtain a molten alloy solution, which is put in Casting in the mold at room temperature, after cooling, the straightening roller is obtained. The weight ratio of the components in the final straightening roller is: 1.5% chromium, 1.5% nickel, 0.3% molybdenum, 0.6% copper, 3.7% carbon, 0.8% silicon %, manganese 0.5%, sulfur and phosphorus content are all less than 0.01%, and the rest is iron.

[0025] Straightening rollers are divided into three structures from the skin to the inside: white mouth, horse steel and gray mouth without boundaries.

Abstract

The invention belongs to the technical field of a steel rolling machine, and particularly relates to an infinite chilled straightening roll for rolling steel. The infinite chilled straightening roll for rolling steel is prepared from chromium, nickel, molybdenum, copper, carbon, silicon, manganese and iron which are used as raw material ingredients according to a certain weight ratio. The infinite chilled straightening roll is simple in preparation, common and available in raw material, low in production cost, good in product performance, simple in technological requirements, suitable for wide popularization and use; the labor intensity of a worker can be effectively reduced; and the production efficiency is improved.

Description

(1) Technical field [0001] The invention belongs to the technical field of steel rolling machinery, in particular to an infinitely chilled straightening roll for steel rolling. (2) Background technology [0002] The straightening roller is an indispensable wear-resistant process spare part for the production of section steel. Its surface is processed into a certain pass. When straightening steel, the surface of the pass is in direct contact with the section steel, and under the action of temperature and pressure, it can withstand rolling and sliding friction. ,Badly worn. [0003] At present, most of the steel straightening rollers in my country are made of nickel-chromium-molybdenum infinite chilled cast iron with a relatively high content. Due to the scarcity and high price of metal nickel resources in our country, the manufacturing cost of straightening rollers is relatively high, which restricts the reduction of the production cost of section steel. There are two w...
