Abstract
A slotted guide comb for the cooling grid used in the calcining system of cement production line is made up through making mould core by use of steel mould and hot resin sand, making external mould by use of cold resin sand, closing, smelting, vertical casting, cutting, grinding plasting balls, machining, and solution heat treatment.
Description
Affiliated technical field
The present invention relates to the manufacture method of grate plate in the cement producing line firing system cooling machine.
Background technology
Grate plate, is carried by hot end for cooler grog when realizing hot grog and cooling air heat exchange as cooling machine important heat exchange and supply unit to cold junction.Basic demand to grate plate is that air-supply is even, prevents wind path partial penetration, short circuit, and the gas circuit smoothness reduces drag losses; On the other hand; require grate plate to have the heat resistant and wear resistant performance,, make it keep rational work-ing life to adapt to cooling machine high temperature abrasion operating mode; grate plate in the past is traditional fluted body grate plate; disclosed as ZL99205461.3 and ZL99205460.5, the system cools effect is not good enough, and power consumption values is big; the cooling air consumption is many; work-ing life is short, and the main shut-down system maintenance time is long, influences production efficiency.
Summary of the invention
The manufacture method that the purpose of this invention is to provide a kind of slit type grate plate, the grate plate of production can overcome above-mentioned shortcoming and defect.
The present invention realizes by following processing step: at the inner chamber of complexity and the seam of combing, the design technology parameter is made mould, adopts punching block, and adding pattern of fever resin sand is heated and produced required special-shaped grate plate core; Adopt cold mould resin sand, make external mold; Mould assembling, fixing, melting, cast, foundry goods once shaped; The foundry goods embryo is through cutting, polishing, shot-peening, mechanical process, after solution heat treatment makes the finished product grate plate.
Before mould assembling is fixing, the high temperature resistant quick drying paint of brushing on model.
About the molten refining to 1600 of raw material ℃, pour into a mould again.
Pouring technology adopts low temperature to water soon, the integral vertical type cast, and once shaped, liquid steel temperature is controlled at 1520 ℃-1550 ℃.
Solution heat treatment is adopted the grate plate chamber type electric resistance furnace of packing into, is heated to 1050 ℃ ± 50 ℃, is incubated three hours, and is air-cooled fast then.
The slit type grate plate that adopts above-mentioned technological method to make, the slit of grate plate is little, and I reaches 2.5mm, has changed in the past the seam of combing is assembled welding, and the seam of combing is inhomogeneous and do not reach the following situation of 3mm.Narrow comb seam has improved the outlet wind speed of grate plate, realizes the high-drag feature of grate plate, and the present like product of its resistance ratios has improved nearly ten times, make grate plate ventilative more even, have higher perviousness, strengthened the deep layer cooling performance, reduced the cooling air consumption; High temperature quench area and heat recovery area at the cooling machine are used the slit type grate plate, and quenching is effective, effectively improves heat recovery rate, and energy conservation and consumption reduction effects is obvious; Adopt solution heat treatment technology simultaneously, strengthened the grate plate creep-resistant property, improved the work-ing life of grate plate.
