Summary of the invention
Purpose of design: avoid the weak point in background technology, design and a kind of can fundamentally solve rich chromium cast iron anti-wear fixed sleeve sand present in circular cone sand making machine and roll sand mouth (Longkou) processed that wall constitutes during sand processed, owing to the abrasion of Longkou wall is caused Longkou wall to be worn into groove by sandstone by sandstone, and then cause whole rich chromium cast iron anti-wear fixed sleeve shortening in service life, the super abrasive conical sand making mechanism sand rolling-compaction port anti-wear fixed sleeve that use cost is high.
Design: in order to realize above-mentioned purpose of design, the present invention is on structure designs:
1, in circular cone sand making machine, sand rolling-compaction port (Longkou) wall hardness processed is respectively higher than the design at other position, is one of the technical characteristic of the present invention.The purpose of do so is: due to sand mouth wall (Longkou) wall processed in existing circular cone sand making machine, sand mouth wall (Long Koubi) processed being i.e. made up of anti-wear movable sleeve (crushing wall) and anti-wear fixed sleeve (rolled mortar wall), on structure designs, anti-wear movable sleeve wall is consistent with the hardness of anti-wear fixed sleeve wall, but the width rolling sand stress processed maximum Longkou periphery (anti-wear movable sleeve wall and anti-wear fixed sleeve wall relative circumferential face) during sand processed is only 5-15 centimetre wide, its periphery bottom, Longkou rich chromium cast iron wall stress is relatively small, thus result in Longkou periphery quick abrasion during sand processed, inevitably form arcs of recesses groove, and then cause whole anti-wear movable sleeve and anti-wear fixed sleeve to be greatly shortened service life, frequently change, the cost of made sand remains high.The hardness of Longkou periphery maximum for stress in circular cone sand making machine is improved by the application, its wearability is made to increase substantially, substantially exceed the wearability of bottom, Longkou rich chromium cast iron, so, not only it is greatly reduced the wear extent of Longkou periphery, and enable the rate of wear of the Longkou periphery of width 5-15 centimetre to keep relative consistent with the rate of wear of bottom, Longkou rich chromium cast iron, both improve the service life of conical sand making mouth, avoid the frequent replacing of conical sand making mouth assembly, significantly reduce again sand cost processed.
2, sand rolling-compaction port (Longkou) periphery processed uses air-cooled, Kou Bian bottom, Longkou to use the design of insulation material insulation Slow cooling, be the present invention technical characteristic two.The purpose of do so is: the application finds through a large amount of tests repeatedly: it is to complete Quenching Treatment when 1010-1030 DEG C that the hardening heat of the Longkou wall of the circular cone sand making machine being made up of anti-wear movable sleeve wall and anti-wear fixed sleeve wall takes temperature scope, and the temperature range of temper softening is at 930-950 DEG C, hardening heat is from the beginning of 1010 DEG C, along with hardening heat raises, hardness raises, when hardening heat is more than 1030 DEG C, hardness declines.This is because along with the rising of heating-up temperature and insulation, carbon and diffusion of alloy elements ability in austenite gradually step up, oversaturated austenite separates out under as cast condition primary carbide, the content making carbon in austenite reduces, thus improve Ms point, convert the austenite to as martensite during quenching, thus hardness improves.When hardening heat is less than 1010 DEG C, primary carbide separates out more, and carbon containing and chrome content in balance austenite are relatively low, and when quenching into martensite, in its martensite, carbon and alloying element content are relatively low, make martensite softer, and hardness is relatively low；When hardening heat is higher than 1030 DEG C, carbon and chromium content when austenite reaches balance are higher, make the stability of austenite increase, but still have partial austenitic to remain during air quenching, so that hardness reduction.The most only when hardening heat is moderate, existing a certain amount of carbon and alloying element in balance austenite, can all quench into again M during quenching and just can obtain higher hardness number.Therefore the application in experiments it is found that:
(1) hardening heat of the Longkou wall of the circular cone sand making machine that anti-wear movable sleeve wall and anti-wear fixed sleeve wall are constituted takes temperature scope is to complete Quenching Treatment when 1010-1030 DEG C, and the temperature range of temper softening is when 930-950 DEG C, when using room temperature air-blast quenching, the cool time of the rich chromium cast iron of insulation material cladding 6-12 hour, rich chromium cast iron anti-wear movable sleeve sand roll wall and rich chromium cast iron anti-wear fixed sleeve sand to roll the hardness after wall cools down completely be 60-63.6HRC, and the hardness of the rich chromium cast iron that insulation material is coated with is 56-58HRC；
