Abstract

本发明是用石灰石砂制作铸钢用冒口易割片，它 既可以用于不用气割的要求不高的铸钢件的中小冒 口，也可用于仍要气割的中大型冒口，还可以与保温 冒口配合使用，代替保温冒口的尺寸稳定层，有利于 减小冒口根部的热节，减少切割面积。

Description

本发明涉及一种铸钢冒口易割片，特别是石灰石砂制作的冒口易割片。
冒口易割片的应用可以节约切割冒口的费用，并避免铸钢件气割时产生的裂纹。已经有陶瓷易割片、石英砂-粘土易割片成功地应用于要求不高的不需气割铸钢件的中小冒口。经检索石灰石砂制作的用于铸钢件的冒口易割片尚未见到密切相关的文献。
本发明的目的是要提供一种石灰石砂制作的用于铸钢件的冒口易割片。
本发明的目的是这样实现的：石灰石砂已成功地用于铸钢件生产的铸型和泥芯的制作，所以也可以用来制作铸钢件的冒口易割片。由于石灰石砂浇注后清砂方便，所以这种冒口易割片不仅可以象其它易割片一样，用于不需气割的要求不高的中小冒口上，而且可以用于仍用气割切除冒口的较大的冒口上，还可以与保温冒口配合使用，进一步减少保温冒口的切割面积。
本发明用作铸钢冒口易割片时，既可以用于不需气割的要求不高的中小冒口，也可以用于比较重要的铸钢件上的使用气割去除的中大冒口。与保温冒口合用时，可代替保温冒口上的尺寸稳定层，有利于减小冒口根部的热节。
本发明的具体结构由以下的实施例及其附图给出。
图一是冒口易割片的剖面图。
本发明是这样实施的;将混拌好的石灰石砂放进模具中制作即可获得相应尺寸的易割片，经干燥后可供使用。
