Summary:The invention provides a preparation method of an anchoring type high-strength chock plug brick for a coal water slurry gasification furnace. The preparation method comprises the following steps: S1, preparing a brick body by using a high-chromium material; s2, an anchoring part is fixed in a cavity in the high-strength brick body, and high-chromium castable is used for pouring the interior of the cavity; and S3, after 12-24 hours of curing at the temperature of 50 DEG C, the plug brick is placed in a drying kiln at the temperature of 100-200 DEG C to be cured and dried for 24-48 hours. The high-strength plug brick has the beneficial effects that the high-strength brick body of the plug brick is made of the high-temperature-resistant high-chromium castable, so that the high-strength plug brick can be fired at high temperature and is low in porosity, high in strength, resistant to scouring and erosion and long in service life; the anchoring part is integrally formed by casting a high-strength castable and a hi
