Abstract
The invention provides a production method of a composite funnel impact guard plate, relating to the technical field of mineral separation and material transportation in mining enterprises. The production process comprises the following steps: forming a casting mould by adopting a resin sand formative technology; placing a high-quality Q235 steel plate in the casting mould; after mould assembling, simultaneously pouring a smelted high chromium iron casting material and high-quality Q235 carbon steel respectively at the two sides of the high-quality Q235 steel plate; after sizing is carried out by using alloying and inoculation, demoulding a cast; and quenching the cast and then tempering. By the method, the internal quality and appearance quality of a product are improved, cost is reduced, the impact resistance of the funnel impact guard plate is improved, service life is long, and maintenance amount is less.
Description
Technical field
The present invention relates to the production technical field that funnel impacts backplate in the defeated material of bargh's ore dressing technical field, particularly its equipment.
Background technology
Just present bargh ore dressing conveying system after the initial fragmentation of the ore of exploitation, is delivered to the workshop through transfer roller.Since bargh's special geographical environment, and the distance of fragmentation and abrasive material workshop section is far and near, can not all be that straight line is carried during conveyor delivery, must be via the funnel transfer.After the initial fragmentation of ore, granularity is still very big, and maximum diameter has 50cm; seeing when conveying belt delivers into funnel has original speed; therefore funnel is formed strong impact, and funnel impact backplate is applied to protection funnel in the funnel exactly, makes funnel do not impacted impaired by mineral aggregate.
The funnel that present domestic 95% above bargh uses impacts backplate and is the manganese steel material, and have defective: (1) toughness and shock-resistance are not strong; (2) wear resisting property is poor; (3) work-ing life is short; (4) maintenance capacity is big, needs normal the shutdown to safeguard and replacing.
Summary of the invention
The production method that the object of the invention is to design a kind of low cost, high impact-resistant compound funnel impacts backplate.
Technological process of the present invention comprises:
1, the preparation rich chromium cast iron waters material: with Fe and each the composition mixed smelting that contains following each mass percent, wherein, C2.0～3.0, Si≤1.4, Mn≤1.6, Cr12.0～20.0, Mo≤4.0, Ni≤3.0, Cu≤1.5, P≤0.10, S≤0.16, V≤1.0, Ti≤1.2;
2, preparation Q235 qualitative carbon steel waters material: with the melting of Q235 qualitative carbon steel;
3, the clean Q235 quality steel plate of preparation: the Q235 quality steel plate through pickling, polishing, is removed surperficial dirt and rusty stain;
4, adopt phenolic sand molding technology to form and water injection molding, at the described built-in Q235 of the going into quality steel plate of injection molding that waters, after the mould assembling, the described rich chromium cast iron that pours into melting in the both sides of Q235 quality steel plate respectively simultaneously waters material and the Q235 qualitative carbon steel waters material;
5, after the typing of employing alloying and inoculation process, with the foundry goods depanning;
6, foundry goods is passed through to quench, pass through temper again.
The present invention adopts phenolic sand molding technology, can improve visual appearance in the product, and particularly the working face rich chromium cast iron has initial high rigidity, has very strong impelling strength and wear resistance with the Q235 qualitative carbon steel of non-working surface after compound again.Adopt new alloying and inoculation process and fusion technology, its working face and non-working surface are combined closely in one.Can make the working face hardness HRC that is formed by rich chromium cast iron reach 58-63, the overall flexibility of the non-working surface that is formed by the Q235 qualitative carbon steel reaches ak 〉=15J/ ㎝
2The present invention has also reduced the cost of a large amount of use high-strength metal material effectively, long service life, and maintenance capacity is few.
The present invention is for guaranteeing working face hardness and wear resistance, and described quenching temperature is 980～1050 ℃.
Embodiment
Production stage:
1, the preparation rich chromium cast iron waters material:
With Fe and each the composition mixed smelting that contains following each mass percent, heat preservation for standby use.
Wherein, C2.0～3.0, Si≤1.4, Mn≤1.6, Cr12.0～20.0, Mo≤4.0, Ni≤3.0, Cu≤1.5, P≤0.10, S≤0.16, V≤1.0, Ti≤1.2.
2, preparation Q235 qualitative carbon steel waters material:
With the melting of Q235 qualitative carbon steel, heat preservation for standby use.
3, the clean Q235 quality steel plate of preparation:
The Q235 quality steel plate through pickling, polishing, is removed surperficial dirt and rusty stain.
4, preparation cast model:
Adopt phenolic sand molding technology, resin sand preparation: should be greater than 9～11 ㎏/㎝ with tensile strength
2And ultimate compression strength should be greater than 26～31 ㎏/㎝
2Quartz sand, solidifying agent, coupling agent and resin, through overmulling system, carry out moulding, molding again, repair type, after sclerosis in 1.5～2.0 hours,, light from doing respectively to type and core brushing alcohol-base paint, stand-by after the thorough drying.
5, cast:
Q235 quality steel plate after watering that injection molding is built-in to go into clean the processing, after the mould assembling, the described rich chromium cast iron that pours into melting in the both sides of Q235 quality steel plate respectively simultaneously waters material and the Q235 qualitative carbon steel waters material.Rising speed is identical when note keeping the both sides cast, avoids a kind of material that waters to puncture median septum and sneak into another kind and water in the material.
6, after the typing of employing alloying and inoculation process, the foundry goods depanning.
7, foundry goods is passed through 980～1050 ℃ of quenchings, pass through temper again.
8, foundry goods dead head, overlap, burr etc. are cleared up polishing.
