[0002] The lining of the high-temperature reformer will use refractory castables, and a certain amount of water will be added during the stirring process during pouring. If the construction process does not pass through the oven, the sudden high temperature in the equipment will be much higher than 100°C when it is used on site, which will make the The moisture inside the castable evaporates rapidly, and the water vapor pressure generated is greater than the bonding force of the castable, resulting in cracking and damage to the castable

The invention relates to a liquefied gas furnace-heating method of a refractory lining castable of a heating furnace module. The liquefied gas furnace-heating method of the refractory lining castable of the heating furnace module comprises the following steps that 1, assembly of the module preparing to be furnace-heated is completed, the top of the module is provided with a temporary chimney, everywhere of the module is sealed tightly by using a refractory material, and burning equipment, air collecting and conveying equipment, air leaking monitor equipment, thermocouples and temperature detector equipment are assembled; 2, ignition is conducted, specially, according to the technology requirements, temperature curve controls changes of temperature, and an furnace-heating process is completed; and 3, equipment is dismantled when the temperature drops to indoor temperature. According to the liquefied gas furnace-heating method of the refractory lining castable of the heating furnace module, fire power of burning of liquefied gas is controlled, the temperature around the castable to be dried is controlled, by using the proper temperature changing curve, free water and bound water in the castable are slowly evaporated, it is ensured that the water content in the castable drops to a safe range, and the fact that high temperature generated during on-site using does not cause cracking and damage of the castable is ensured.
Description
technical field [0001] The invention relates to a liquefied gas oven method, in particular to a liquefied gas oven method for heating furnace module refractory lining castables. Background technique [0002] The lining of the high-temperature reformer will use refractory castables, and a certain amount of water will be added during the stirring process during pouring. If the construction process does not pass through the oven, the sudden high temperature in the equipment will be much higher than 100°C when it is used on site, which will make the The moisture inside the castable evaporates rapidly, and the water vapor pressure generated is greater than the bonding force of the castable, resulting in cracking and damage to the castable. Contents of the invention [0003] The present invention aims to overcome the defects of the prior art, and provides a liquefied gas oven method for heating furnace module refractory lining castables. The high temperature generated during the...
