A method for a simulation test of the influence of alkali metal on coke degradation belongs to the field of blast furnace ironmaking technology. Aactive carbon powder and alkali carbonate powder are mixed and added into a corundum crucible; the crucible is placed on the upper part of a high-alumina ball at the bottom of a high temperature reaction vessel; a porous permeable corundum gasket is placed on the corundum crucible; three high temperature resistant corundum branch pipes with a height of 30-60 mm are placed on the gasket; a permeable gasket is placed above the corundum branch pipes; acoke sample is placed on the permeable gasket; after the sample is in place, the sample is heated and argon is pumped in to discharge air in the reaction vessel; when the temperature in the reaction vessel reaches 1200 DEG C, alkali metal vapor is generated; the sample is cooled to room temperature with the protection of argon, and the coke adsorbed with alkali vapor is inspected and analyzed. The advantages ...

A sliding hammer for a poking port of a blast furnace belongs to the technical field of tools for operations in front of the blast furnace, and comprises a main rod, a front baffle plate, two lug hooks, a sliding hammer, a rear baffle plate, a handle and a hinge. The front baffle plate is welded to a two thirds position of a front section of the main rod which is a steel rod, the handle is welded to the tail end of the main rod, the rear baffle plate is connected with the handle, the sliding hammer is mounted between the front baffle plate and the rear baffle plate, the two lug hooks are welded onto the sliding hammer, and the hinge is connected with the sliding hammer through the lug hooks. The sliding hammer for a poking port of a blast furnace has the advantages that the problem of forced off-blast treatment due to difficulty in port poking is avoided, and poking without stopping blast is realized. Labor intensity is relieved for workers, production management is convenient, production ...
