Description

[TITLE] COMPOSITION FOR COATING STEELMAKING DUST BRIQUETTE AND STEELMAKING DUST BRIQUETTE [TECHNICAL FIELD] A composition for coating a steelmaking dust briquette and a steelmaking dust briquette are disclosed. More particularly, a composition for coating a steelmaking dust briquette including a cellulose ether compound and a steelmaking dust briquette are disclosed. [BACKGROUND ART] A steel manufacturing process is divided into an iron making process to produce crude steel using iron ore and coal and a steel making process to increase purity of the crude steel. A large amount of iron and selectively metal components such as zinc remain in steelmaking dust produced in the steel making process. While the steelmaking dust including metal components has been discarded conventionally, technologies to reuse the steelmaking dust have been developed recently. The steelmaking dust has a non-uniform particle size distribution and includes various components. One of the representative techniques to reuse the steelmaking dust is a technique of adding briquettes obtained by press-molding the steelmaking dust to the steel making process again. Most steel companies have reused steelmaking dust in the form of briquettes. The briquettes are transported using vehicles and conveyer belts for recycling, and an aqueous solution of sodium silicate is used to coat the briquettes in order to reduce dust generated while the briquettes are transported. However, although dust is reduced by coating the briquettes with the aqueous solution of sodium silicate, a nozzle used to spray the aqueous solution of sodium silicate may be blocked or the aqueous solution of sodium silicate may be limitedly coated only on the surface of the briquettes. Thus, dust is still generated. [DETAILED DESCRIPTION OF THE INVENTION] [TECHNICAL PROBLEM] An aspect of the present invention is to provide a composition for coating a steelmaking dust briquette including a cellulose ether compound. Another aspect of the present invention is to provide a steelmaking dust briquette including the composition for coating a steelmaking dust briquette. [TECHNICAL SOLUTION] According to an aspect of the present invention, there is provided a composition for coating a steelmaking dust briquette including a cellulose ether compound. 1 7701770_1 (GHMatters) P103024.AU The cellulose ether compound may include at least one compound selected from the group consisting of methyl cellulose (MC), hydroxypropylmethyl cellulose (HPMC), hydroxyethylmethyl cellulose (HEMC), and hydroxyethyl cellulose (HEC). The cellulose ether compound may have a viscosity of 100 to 60,000 cps. An amount of the cellulose ether compound may be in the range of 0.45 to 5 parts by weight based on 100 parts by weight of the composition for coating a steelmaking dust briquette. The composition for coating a steelmaking dust briquette may further include 10 to 100 parts by weight of a binder based on 100 parts by weight of the cellulose ether compound. The binder may include gelatinized starch, and the gelatinized starch may include at least one compound selected from the group consisting of corn starch, waxy corn starch, and potato starch. The composition for coating a steelmaking dust briquette may further include water. According to another aspect of the present invention, there is provided a steelmaking dust briquette including: a body; and a coating layer coated on the body, wherein the coating layer includes a cellulose ether compound. The coating layer may further include 10 to 100 parts by weight of a binder based on 100 parts by weight of the cellulose ether compound. The coating layer may have a thickness of 10 to 100,000 ym. [ADVANTAGEOUS EFFECTS OF THE INVENTION] Since a composition for coating a steelmaking dust briquette according to an embodiment of the present invention includes a cellulose ether compound, a phenomenon in which a spray nozzle is blocked during a coating process of the steelmaking dust briquette may be prevented. Also, since not only the surface of the steelmaking dust briquette but also pores thereof are coated, dust generated from the steelmaking dust briquette while the briquette is transported may be reduced, and strength of the steelmaking dust briquette may be increased. [MODE OF THE INVENTION] Hereinafter, a composition for coating a steelmaking dust briquette according to an embodiment of the present invention will be described in detail. 2 7701770_1 (GHMatters) P103024.AU The composition for coating a steelmaking dust briquette according to an embodiment of the present invention includes a cellulose ether compound. As used herein, the term steelmaking dust' refers to blast furnace dust, electric arc furnace dust, or a mixture thereof. Since the cellulose ether compound is highly soluble in water and is not precipitated on an inner surface of a nozzle while being sprayed through the nozzle in the form of an aqueous solution, the nozzle is not blocked. In addition, when coated on the steelmaking dust briquette, the cellulose ether compound not only covers the surface of the steelmaking dust briquette, but also infiltrates into pores of the steelmaking dust briquette, and thus the cellulose ether compound prevents dust generation from the steelmaking dust briquette while the steelmaking dust briquette is transported and increases strength of the briquette. The cellulose ether compound may include at least one compound selected from the group consisting of methyl cellulose (MC), hydroxypropylmethyl cellulose (HPMC), hydroxyethylmethyl cellulose (HEMC), and hydroxyethyl cellulose (HEC). The cellulose ether compound may have a viscosity of 100 to 60,000 cps (centipoise). As used herein, the term 'viscosity of the cellulose ether compound refers to a viscosity of an aqueous solution of the cellulose ether compound having a concentration of 2 wt% measured at 20±0.1 C by using a DV- I +Pro manufactured by Brookfield. An amount of the cellulose ether compound may be in the range of 0.45 to 5 parts by weight based on 100 parts by weight of the composition for coating a steelmaking dust briquette. When the amount of the cellulose ether compound is within this range, a steelmaking dust briquette having increased strength may be obtained with reduced dust generation. The composition for coating a steelmaking dust briquette may further include 10 to 100 parts by weight of a binder based on 100 parts by weight of the cellulose ether compound. When the amount of the binder is within this range, manufacturing costs for the composition for coating a steelmaking dust briquette may be reduced by reducing an amount of the cellulose ether compound used therein, drying speed of the composition for coating a steelmaking dust briquette may be increased, and a steelmaking dust briquette having increased strength may be obtained with reduced dust generation. The binder may include gelatinized starch, and the gelatinized starch may include at least one compound selected from the group consisting of corn starch, waxy corn starch, and potato starch. The composition for coating a steelmaking dust briquette may further include water. An amount of water may be an amount obtained by excluding the amounts of the cellulose 3 7701770_1 (GHMatters) P103024.AU ether compound and the binder from a total amount of the composition for coating a steelmaking dust briquette. A steelmaking dust briquette according to another embodiment of the present invention includes a body and a coating layer coated on the body. The body refers to parts of the steelmaking dust briquette that is not coated with the composition for coating a steelmaking dust briquette. The coating layer includes a cellulose ether compound. The coating layer may further include 10 to 100 parts by weight of a binder based on 100 parts by weight of the cellulose ether compound. When the amount of the binder is within this range, costs for coating the body may be decreased by reducing the amount of the cellulose ether compound, time for coating the body may be shortened, and a steelmaking dust briquette having increased strength may be obtained with reduced dust generation. The coating layer may have a thickness of 10 to 100,000 ym. When the thickness of the coating layer is within this range, a steelmaking dust briquette having increased strength may be obtained with reduced dust generation at relatively low costs. Hereinafter, embodiments of the present invention will be described in further detail with reference to the following examples. These examples are for illustrative purposes only and are not intended to limit the scope of the invention. Examples Preparation Example 1: Preparation of Uncoated Steelmaking Dust Briquette 10 kg of steelmaking dust collected from a domestic steel company was press-molded using a Briquette machine (JEIL MACHINERY, custom-made) to prepare 30 steelmaking dust briquettes. An average weight of the prepared steelmaking dust briquettes was 20 g. Examples 1 to 5 (Preparation of Composition for Coating Steelmaking Dust Briquette) A cellulose ether compound, gelatinized starch, and water were mixed to prepare a composition for coating a steelmaking dust briquette. In this case, an amount of water was adjusted such that a total amount of the cellulose ether compound and the gelatinized starch was 2 parts by weight based on 100 parts by weight of an amount of the composition for coating a steelmaking dust briquette. Types and amounts of the cellulose ether compound used in the respective examples and amounts of the gelatinized starch are shown in Table 1 below. In addition, viscosities of the compositions for coating a steelmaking dust briquette prepared according to the respective examples were measured by using a DV-I+Pro manufactured by Brookfield, and the results are shown in Table 1 below. 4 7701770_1 (GHMatters) P103024.AU [TABLE 1] Example 1 Example 2 Example 3 Example 4 Example 5 HPMC*l (parts by weight) 90 80 0 0 0

As a result, coated steelmaking dust briquettes were obtained. Comparative Example 1: Preparation of Composition for Coating Steelmaking Dust Briquette and Coated Steelmaking Dust Briquette Sodium silicate (Na 2 O(SiO 2 ), Sigma Aldrich) was dissolved in water to prepare an aqueous solution of sodium silicate having a concentration of 2 wt%. Then, the aqueous solution of sodium silicate was coated on the steelmaking dust briquettes prepared according to Preparation Example 1 to have a thickness of 30 ym by spraying and dried at 60 C for 1 hours. As a result, a coated steelmaking dust briquette was obtained. Evaluation Example Evaluation Example 1 Degrees of dust generation and drop strengths of the coated steelmaking dust briquettes respectively prepared according to Examples 1 to 5 and Comparative Example 1 were evaluated using methods described below, and the results are shown in Table 2 below. (Evaluation of Degree of Dust Generation) After the coated steelmaking dust briquettes were respectively rubbed with a hand, degrees of dust adhered to the hand were evaluated by visual observation using a 5-point scale. In this case, a lower grade indicates a smaller degree of dust generation. (Evaluation of Drop Strength) 5 7701770_1 (GHMatters) P103024.AU The coated steelmaking dust briquettes were respectively dropped at a height of 5 m five times. Then, a total weight of fragments having a size of 10 mm or greater among remaining fragments of each of the coated steelmaking dust briquettes was expressed as a percentage with respect to a weight of each of the coated steelmaking dust briquettes measured before dropping, and the value was evaluated as a drop strength. In this case, a higher value indicates higher drop strength.
