Abstract
The invention provides a ball press roll surface material formula, and aims to solve the problems that the chemical components of a ball press are not changed due to limit of the materials, the service life is short and the production cost is high. The ball press roll surface material formula is characterized by comprising the following components in percentage by mass: 0.9-1.1% of C, 1.7-1.9% of Cr, 0.2-0.4% of Mn, 0.4-0.6% of Si, 0.15-0.35% of Ni, 0.1-0.3% of Cu, 0.1-0.3% of Mo, 0.02-0.04% of S, and the balance of Fe and other elements. According to the ball press roll surface material formula, forging is replaced by casting to change chemical components needed by different roll surfaces from the materials, so that the mechanical performance, hardness, wear resistance and corrosion resistance of a ball press roll surface can be improved, the service life is prolonged and the production cost is lowered, the research and development space for producing different materials of roll surfaces can be enlarged so as to furthest develop and adapt to the market demand.
Description
Technical field
The present invention relates to shaped coal technology field, especially a kind of ball press roller leather material formula.
Background technology
At present, China energy problem is severe, and moulded coal obtains as the one of Filter Tuber For Clean Coal production technology and greatly develops, and along with the development of briquetting process, the wearing quality of molding device and ratio of briquetting are extensively concerned; Ball press roller skin is a requisite important component in ball press type coal equipment, and ball press roller skin determines the shape of ball press compression moulding; Ball press roller skin generally adopts 9 chromium 2 molybdenums or 65 Mn forging materials in the market, limitation because of material can not change its chemical composition, when suppressing different material in ball press course of normal operation, life-span of roller skin is not at 10 days to 6 months etc., life-span is short, production cost is high, greatly reduces working efficiency.
" a kind of ball press pressure roller and preparation method thereof " of the patent No. 2013105192287, the per-cent of its moiety is: C2.8 ~ 3.2%, Mn0.5 ~ 1.2%, Si0.25 ~ 0.6%, Cr19.0 ~ 23.0%, Mo1.0 ~ 1.5%, Cu0.7 ~ 1.0%, Re0.05 ~ 0.10%, S < 0.040% and P < 0.080%, and surplus is iron and other elements; Preparation method is: the materials such as steel scrap, electrolytic copper, ferrochrome, molybdenum-iron, ferromanganese, ferrosilicon are heated in proportion in middle frequency furnace melted after, add casting after rare earth silicon manganese alloy and pure aluminium powder again, then can preparation technology be completed after special process heat treatment process; Improve wear resistance and stretch-resistance, long service life; Elemental composition after its casting is high ferrochrome.And a kind of ball press roller leather material formula that the present invention proposes, its elemental composition after casting is tool steel, and its mechanical property, hardness, fastness to rubbing and preservative property are more superior to above-mentioned patented invention.
Summary of the invention
Its chemical composition is can not change in order to solve market upper pressing ball machine because of the limitation of material, life-span is short, the problem that production cost is high, a kind of ball press roller leather material formula is proposed, its casting and forging, the chemical composition of differential roller skin requirement is changed from material, not only increase the mechanical property of ball press roller skin, hardness, fastness to rubbing and preservative property, increase work-ing life, reduce production cost, and research and development space is increased to the roller skin producing different material, make it farthest be developed, meeting the market requirement.
A ball press roller leather material formula, is characterized in that: adopt following quality proportioning: C:0.9 ~ 1.1%, Cr:1.7 ~ 1.9%, Mn:0.2 ~ 0.4%, Si:0.4 ~ 0.6%, Ni:0.15 ~ 0.35%, Cu:0.1 ~ 0.3%, Mo:0.1 ~ 0.3%, S:0.02 ~ 0.04%, surplus is Fe and other elements.
The preferred mass proportioning of ball press roller leather material formula is: a C:1.0%, Cr:1.8%, Mn:0.3%, Si:0.5%, Ni:0.25%, Cu:0.2%, Mo:0.2%, S:0.03%, and surplus is Fe and other elements.
