FIREPROOF CASTING INSERT MADE OF FIREPROOF RAW MATERIALS AND FIREPROOF CASTING PRODUCED FROM THE INSERT |
摘要 |
The invention relates to a fireproof casting insert made of at least one fireproof raw material, in particular at least one basic fireproof material, in particular, sinter magnesia and/or melt magnesia (MgO), in addition to at least one cold hardened primary binding agent and at least one secondary binding agent producing a carbon bond that is thermally hardened under the effect of temperature. From the broken raw material granulates, predefined core fractions having a predefined raw material and grain formation optionally, by adding flour cores, is prepared to form an amount of raw material. The cold bound primary binding agent is a powdery lignin bond and/or a liquid, dual-component, cold hardened resin binding agent. |
