The invention discloses a converter slag resource utilization apparatus and a converter slag resource utilization technology, and belongs to the technical field of metallurgy. The apparatus comprises: a converter slag tank used for hot charging and transshipment of converter slag; a slag hardening and tempering kiln, a clarification kiln and a tin tank which are sequentially connected; a concurrent heating device and a bottom blowing stirring device which are arranged in the slag hardening and tempering kiln; an auxiliary material feeding device used for adding auxiliary materials to the slag hardening and tempering kiln; and a transshipping device used for transshipping the converter slag tank. The technology comprises the following steps: carrying out hot charging on high temperature converter slag by using the converter slag tank, mixing the high temperature converter slag, carbon saturated molten iron and auxiliary materials in the slag hardening and tempering kiln, heating and stirring above materials, filling the clarification kiln with the obtained mixture, homogenizing the clarified mixture, allowing the homogenized mixture to enter the tin tank, cooling the mixture, and carrying out post-treatment to obtain a final product. Microcrystalline glass and other products with high added values can be produced by directly using physical heat carried by the high temperature converter slag and only using a small amount of energy, so the production cost of the microcrystalline glass is greatly reduced, and the utilization efficiency and the utilization quality of the converter slag are fundamentally improved.
