Regenerator checker deformation analysis of the causes


01250l13O01282I900 / 2 * 000l852 regenerator checker analysis of the anatomical material regenerator checker brick samples taken from the physical properties and chemical composition determination found that clay brick lattice the chemical composition and physical properties have undergone varying degrees of change. In addition to AlO and Feoa significantly increased, the low melting point substances such as Kzo, NaO, CaO,[link widoczny dla zalogowanych], Mgo, also have increased significantly, the low melting temperature of no more than l200U crystal material, the gradually melting, deformation,[link widoczny dla zalogowanych], secondary to the formation of Mo stone, brick to brick lattice expansion,[link widoczny dla zalogowanych], deformation, and the results shown in Table 3.

Subjectwords: Ascensionpipe-SealWaterseal-Improvement1 day, most of the coke plant there is an increase in tube seal device improved water seal device structure following questions. A ... ... ... ... ~ (1) high temperature seal seat,[link widoczny dla zalogowanych], poor sealing between the seat and lid, once the water supply within the water quickly evaporated Block, a large number of escaped gas fire that caused water seal seat,[link widoczny dla zalogowanych], cover deformation and the water supply valve damage. (2) The seal of the water cycle management as the inconvenience of operation difficult to achieve, so most of the coking plant is to seal the pool water into the coke quenching, coke quenching steam of pollutants with the atmosphere and scattered in the surrounding soil. To solve the above problem, we in the new design of the original water seal device was improved. Figure l shows, the seal seat wall to wall by a single jacket. Jacket filled with fire-resistant fibers, fiber thickness of about 30mm. Thus, contact with water, a significant reduction in wall temperature of the water seal to reduce evaporation of water, its consumption will be reduced accordingly. Water to cover the spherical cavity filled by the refractory fiber in order to reduce heat loss and cover deformation. Here the contact area and cover the processing, to reduce the contact surface, so that the formation of contact of seat and cover spherical universal seal. Even if the lid malposition, still maintain a good seal because the seal before the seal was set for a mechanical seal. 3 Conclusions (1) coke oven regenerator checker brick in the long-term deformation under high temperature, low melting point material melts the secondary mullite formation expansion caused by the brick, so controlling with air temperature and reduce the regenerator top Brick low melting point material content in the clay can reduce the degree of deformation of the quality checker. (2) control the deformation of regenerator checker brick oven on the improvement of the normal heating oven to maintain normal production capacity, improve the quality of coke is very useful.
