研制成功一种新型烧煤的炉组，由热煤气炉、熔化炉和退火炉串联组成。
The line is composed of hot gas generator, melting furnace and annealing furnace in series.
并以煤气罩式退火炉为例，建立了该过程的数学模型，提出了有煤气压力干扰补偿方案。
The mathematic model of this process is built based on a covered anneal gas boiler, and a disturbance compensation method is provided.
三层真空复合底，比普通焊接复合底更耐用，煤气炉等明火炉灶使用；
III. Tri-ply vacuum base, more stronger and efficient heat conduction, can use on gas or electric ranges;
