Color: The heartwood of Merbau is typically a brownish-orange when first cut and becomes a darker reddish brown upon exposure to air. KelaiWood , https://www.kelaiwoodens.com
Industrial furnace furnace technology :
The lifespan and safety of the furnace are closely related to the furnace technology. When paving the furnace, first check whether the coil is damaged. If it is, apply the insulating varnish to the damaged part and repair it; then repair the furnace wall with water glass refractory mud, and clean the furnace wall and the bottom of the furnace; Dimensional cut mica board, alarm stainless steel net, asbestos cloth; use copper core wire to connect the alarm stainless steel mesh out of the furnace coil, and then use three rising rings to rise under the furnace wall of the asbestos cloth. Tight; the paved stove should be covered to prevent debris from falling into it.
Industrial furnace oven process :
Oven is an important part. The oven is to obtain the process of sintering the layer. The quality of the sintered layer directly affects the service life of the furnace. After the furnace cavity is built, the oven should be immediately performed; before the oven, check whether the electrical equipment and the cooling water system are normal; The furnace should be carried out in strict accordance with the oven process. The oven process is a key factor in the oven process. The specific points are as follows: 1. To control the heating rate, especially in the early stage of the oven, if the heating rate is too fast, the moisture in the lining is too fast to form cracks, which makes the industrial furnace Life expectancy is greatly reduced. 2 When the furnace lining is heated to 573 ° C, the β-quartz in the lining is rapidly converted to α-quartz, and the volume expansion is 0.82%. The temperature continued to rise and the α-quartz was converted to α-scaly quartz at 870 ° C with a volume expansion of 16%. If the expansion is too fast during the quartz phase transformation, it will easily cause cracks or even flaking. Therefore, when heating to 600 °C at 400 °C, the heating rate should be slowed down, and at 870 °C, it should be kept for 1h to 2 hours, so that it can be slow and complete. Phase change. 3 The final stage of the oven is sintering and heat preservation. The sintering temperature depends on the specific refractory material. It is generally desirable to obtain a sintered layer having a thickness of 30% of the thickness of the lining. Generally, the sintering temperature is higher than the temperature of the tapping iron by 50 ° C to 100 ° C.
Therefore, the use of the correct standard paving and oven processes can increase the life of the furnace.
