西德现用一种新的盛钢桶加热器(Mapeko公司制造),能使桶底温度达到1100～1200℃,甚至更高些的温度。可以对燃烧混合物作出固定调整,在达到规定温度后,燃烧器自动切断减少到其最大能力的25％。盛钢桶口用热屏隔热,能保持规定温度。用一种特殊类型火焰,有50％以上能源消耗在焰长的末端1/3部分,使桶底温度在40～60分钟内达到要求。操作简易安全,有较高的工作效率,能显著
In West Germany, a new ladle heater (manufactured by Mapeko) was used to bring the bottom temperature to 1100-1200 ° C, and even higher. The combustion mixture can be set to a fixed value and automatically cut off to 25% of its maximum capacity after the specified temperature has been reached. Sheng barrel mouth with hot screen insulation, to maintain the required temperature. With a special type of flame, more than 50% of the energy is consumed in the last 1/3 of the flame length, so that the temperature at the bottom of the tank is within 40 to 60 minutes. Simple and safe operation, high work efficiency, can be significant
