煤礦軌枕模具在熱處理后的表面常常會出現(xiàn)一些軟點(diǎn)，出現(xiàn)軟點(diǎn)的原因有在熱處理前的表面有氧化皮、銹斑及局部的脫碳和淬火加熱后，冷卻淬火介質(zhì)選擇不當(dāng)，淬火介質(zhì)中的雜質(zhì)過多或老化兩個原因，出現(xiàn)的軟點(diǎn)會影響模具的耐磨性，減少了模具的一個使用壽命。煤礦軌枕模具具備有綠色環(huán)保的高產(chǎn)品，低消耗，質(zhì)量好，價(jià)格優(yōu)。煤礦軌枕模具要想讓我國建筑行業(yè)成為領(lǐng)先者,并加強(qiáng)創(chuàng)造能力,加快提高軌枕模具企業(yè)的國際競爭力,我國許多工業(yè)行業(yè)產(chǎn)量居世界第一,但是分散在許多軌枕模具企業(yè)中,缺少具有國際競爭力的大企業(yè),因此我們應(yīng)當(dāng)加強(qiáng)自主品牌建設(shè),力爭在局部領(lǐng)域?qū)崿F(xiàn)技術(shù)創(chuàng)新的有效突破,為煤礦軌枕模具產(chǎn)業(yè)進(jìn)入高端領(lǐng)域贏得先機(jī)。Some soft spots often appear on the surface of coal mine sleeper mould after heat treatment. The reasons for the soft spots are that the surface before heat treatment has oxide scale, rust spots, local decarburization and quenching. After heating, the cooling quenching medium is improperly selected, and there are too many impurities or aging in the quenching medium. The soft spots will affect the wear resistance of the mould, A service life of the die is reduced. Coal mine sleeper mould has high green and environmental protection products, low consumption, good quality and excellent price. In order to make China's construction industry a leader, strengthen the creativity and accelerate the improvement of the international competitiveness of sleeper mold enterprises, the output of many industrial industries in China ranks first in the world, but scattered among many sleeper mold enterprises, there is a lack of large enterprises with international competitiveness. Therefore, we should strengthen the construction of independent brands, Strive to achieve effective breakthroughs in technological innovation in local fields and win the first opportunity for the coal sleeper mould industry to enter the high-end field.
