Description

A kind of blast-furnace tuyere inwall welder
Technical field
This utility model relates to metallurgical equipment manufacturing technology field, particularly relates to a kind of blast-furnace tuyere inwall welder.
Background technology
Blast-furnace tuyere is a key spare parts during manUfaCtUre of pig iron produces, and blast-furnace tuyere is in the high temperature cupola well of more than 2000 DEG C Radiation and convection of heat impact, the blast-furnace tuyere front end of inside bearing high-temperature region are also followed by liquid slag ferrum and the high speed of about 1500 DEG C Washing away of the red-hot material of ring motion, by 900 DEG C~the hot blast of 1300 DEG C in blast-furnace tuyere, is subject to again in burn cycle district simultaneously The infiltration to air port to strong Oxidation and trace element, is also ground by the high speed of coal dust under the conditions of this external coal injection Damaging, these unfavorable factors all exacerbate the broken invalid of blast-furnace tuyere.And the broken invalid of blast-furnace tuyere causes smelting cost to increase Add, quality reduces, and even needs to shut down replacing air port and causes blast fumance efficiency to decline.
At present, the main method using plasma thermal sprayed both at home and abroad, by powder or thread strengthening material at high temperature and high speed Jet in melt, spray on the inside and outside wall of burner hearth side, air port formed strengthened coat.But it typically can be only formed machine with matrix Tool combines, and in cooling procedure, can produce make both because coating is different from the thermal coefficient of expansion of matrix on both faying faces The stress separated, and with the increase of coating layer thickness, this stress, by cumulative rises, eventually results in coating and is combined with tuyere body Destroy and make both separate, therefore, it is difficult to obtain thick coating.And if spraying relatively shallow layer, because coating is relatively thin and hole is difficult to keep away Exempt from, cause intensity not enough, it is difficult to the heat bearing high hot coal powder is washed away and fragile.The service life of blast-furnace tuyere is shorter.
Therefore propose in blast-furnace tuyere for blast-furnace tuyere actually used situation aborning and main failure forms Wall uses the process of electric arc cladding high temperature wear resistant alloy material.Propose the material knot of " transition zone+surface layer abrasion-proof alloy " Structure, carries out equidistant micro-hardness testing along molten long-pending direction to strengthening sample, and result shows that sample microhardness is hard along molten long-pending direction Degree is incremented by gradient;Wear test shows, the wearability of skin-material structure is significantly larger than red copper at normal temperatures;Thermal shock resistance Experimental result shows, the thermal shock resistance of sample is also much better than plasma spray coating process, it is seen that use electric arc cladding high-temperature wearable The process of alloy material can effectively extend the service life of blast-furnace tuyere, but existing electric arc cladding high temperature wear resistant alloy It is poor that material technology is applied to safety during blast-furnace tuyere inwall.
