Abstract
The invention discloses a thermal treatment technique for an anti-wear food tool material. The material is 42CrMo and comprises components in percentage by weight: 0.40-0.42 of C, 0.60-0.62 of Cr, 0.12-0.15 of Mo, and the balance of Fe and inevitable impurities. A quenching technique comprises the steps: heating the material to 550+/-10DEG C, insulating heat for 60+/-5 minutes, then continuously heating to 880+/-10 DEG C, preserving heat 90+/-5 minutes, and carrying out water cooling. The hardness of the material is HB:280, so that the material can complete the breaking, grinding or agitating operations of food active ingredients, overcome the wear and impact in processing, and prevent fine grains on the surface from falling and polluting food active ingredients.
Description
Technical field
The present invention, relevant for food processing field, particularly has the thermal treatment process of the tool material that prevent the mechanical material wearing and tearing.
Background technology
It has industrialization, mechanize, automatization and standardized characteristics the relative traditional food industry of foodstuffs industry.It replaces traditional manual processing and hand operation usually, uses the processing that heavy mechanical equipment carries out industrialization, automatization instead.From raw-material collection, select, clean, broken processing, precision refinement etc. all adopt mechanical means to carry out.And extensively adopt the main body of metallic substance as each parts, instrument in existing mechanical means.
Therefore, no matter preliminary working or precision work in food-processing, have wearing and tearing, form and tinyly come off and sneak into the risk in foodstuffs material with the contacted instrument of food.
For a particular job requirement of foodstuffs industry, selecting rational intensity, hardness and ductility and toughness material is exactly technical problem to be solved in this area.
Sneak among food for solving corresponding impurity or objectionable impurities, a kind of wear-resisting safety food machinery tool material and complete processing thereof need to be provided, ensure health of human body.
Summary of the invention
The invention provides a kind of thermal treatment process of abrasionproof food tool material, it is characterized in that: the material of described instrument is 42CrMo, and the mass percent of its material composition is: C:0.40 ~ 0.42; Cr:0.60 ~ 0.62; Mo:0.12 ~ 0.15; All the other are Fe and inevitable impurity; And quenching technology is: described material is warmed up to 550 ± 10 ℃, is incubated 60 ± 5 minutes, then continue to be warmed up to 880 ± 10 ℃, be incubated 90 ± 5 minutes, water-cooled.
Should be by described material made instrument will be used to directly to contact with the raw material of food, and complete contacted described food raw material carried out to Physical Processing.
The hardness of this wear-resisting food machinery material is HB:280, has higher surface hardness, can overcome the wearing and tearing of foodstuff raw material to tool material in food-processing, prevents that the tool surfaces material is worn down to fine particle and comes off into the contaminated food products raw material.
Embodiment
The invention provides a kind of thermal treatment process of abrasionproof food tool material, abrasionproof food tool material provided by the present invention are characterised in that: the material of described instrument is 42CrMo, and the mass percent of its composition is: C:0.40 ~ 0.42; Cr:0.60 ~ 0.62; Mo:0.12 ~ 0.15; All the other are Fe and inevitable impurity; And quenching technology is: described material is warmed up to 550 ± 10 ℃, is incubated 60 ± 5 minutes, then continue to be warmed up to 880 ± 10 ℃, be incubated 90 ± 5 minutes, water-cooled.
Adopt the abrasionproof food tool material that disclose in the present invention after above-mentioned processes, its tensile strength had meets: 800MPa, yield strength meets: 700MPa, hardness HB:280.
By described material, made instrument will be used to directly to contact with the raw material of food, and described instrument is driven and is used to by food machinery and directly contacts with food, and complete contacted described food raw material is carried out to Physical Processing.
For example, this abrasionproof food tool applications is in the preliminary working field, and its described instrument is driven and is used to by food machinery and directly contacts with food, and has and food is carried out to the Physical Processing operations such as fragmentation, pulverizing, stirring.These operations need to adopt corresponding mechanical means to drive the instrument of specified shape or structure directly to contact with food, and food has hard shell, kernel, seed and/or impurity even sometimes, corresponding food processing tool will the long-term working conditions in being polished.
Therefore, in the preliminary working stage, by described material made instrument by least same shell, kernel, seed even in impurity one of contact and physical friction.
In addition, these abrasionproof food tool material are applied to the precision work field, this instrument directly with the contacted operations such as food, solvent, additive, and the materials such as solvent, additive also will be to the impact of the machining tool formation physics and chemistry that has been polished.
Therefore, in the precision work stage, by described material made instrument during at least same food raw material, food solvent, foodstuff additive etc. are contacted one of contact and physical friction.
Its performance of abrasionproof food instrument of being made by this material, meet safety, the hygienic requirements of food machinery in preliminary working, precision work, can keep the wear resisting property of its elaboration face, can not cause the surface metal material to come off and sneak among food raw material.
Should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments, should be appreciated that non-limiting embodiments describes as just example.The protection domain of the essence that the application will require more is embodied in the scope that independent claim provide, with and dependent claims.
